AB  - Incorporation of Rare earth elements (RE), which are known as good corrosion inhibitors, could be promising for extending a useful life of metallic coatings. In this work electrodeposited Zn-Co-RE composite coatings (RE=La, Sm, Y) were studied with the aim of defining the optimal parameters for obtaining the coatings with improved corrosion stability. The coatings were deposited galvanostatically, at different current densities, from chloride electrolyte at 25 °C. The chemical content of composite coatings was determined by energy dispersive X-ray analysis (EDS), morphology by scanning electron microscopy (SEM) and corrosion stability by electrochemical impedance spectroscopy (EIS). It was shown that deposition is of anomalous type. Zn-Co-Sm coatings contain K that forms a water soluble complex with Sm that easily dissolves leaving a porous coating of a poor corrosion stability. Since small deposition current density favors greater Sm, as well as K, incorporation, coatings obtained at greater current density showed better corrosion stability with short self-healing effect. Contrary, Zn-Co-Y coatings deposited at smaller current densities, with greater Y amount, exhibited excellent selfhealing effect with considerable increase in impedance values.

AB  - Although rare earth (RE)-based conversion coatings have become a viable green substitute for hazardous chromiumcoated
ones, research in academia and industry is still ongoing to determine how they provide corrosive resistance.
Numerous smart coatings incorporate nanoparticles of metal and metal oxides, offering diverse functional attributes
and improved performance. In areas of the substrate that have been harmed by mechanical action or chemical
interaction in a corrosion environment, these coatings may allow the substrate to heal itself [1-3]. One way to do selfhealing
is to incorporate inhibitor species into the coating formulation directly or encapsulate them in containers that
are responsive to certain external stimuli. The corrosion protection afforded by the RE element and the small-scale
phenomenon of corrosion inhibition conferred by RE doped pure Zn and Zn-Co alloy coatings are the main subjects
of this work, with the aim of determining the RE contribution in corrosion protection either alone or in synergy with
Co. Both Zn and Zn-Co alloy coatings are designed to modify the steel surface and offer effective corrosion
protection, often as a stand-alone coating or as a as a base layer for organic top coats.
The chloride plating solutions containing Ce, Nd, or Sm were used to electrodeposit the Zn-RE and Zn-Co-RE
protective composite coatings. As the primary drawback in the particle inclusion via electro-codeposition methods,
particle agglomeration was minimized by adding RE to the plating solutions through synthetic RE-thioglycolate
complexes and bath stability was determined as opposed to oxide containing or commercial powder containing
ones. The protective qualities and self-healing capability were observed to be influenced by the type of RE, its
reservoir, solubility in the composite coating, and surface morphology. The impact of these parameters was
evaluated and compared using a multi-analytical approach, which involved dynamic light scattering, attenuated
total reflectance, Fourier-transform infrared spectroscopy with ATR, nuclear magnetic resonance, Scanning Kelvin
Probe Force Microscopy, open circuit potential measurements, and electrochemical impedance spectroscopy. It
was shown that adjusting various electrodeposition parameters such as deposition current density, type of
electrolyte agitation, and the source of rare earth elements can influence the RE content within the coating. The
inclusion of rare earth elements in both Zn and Zn-Co coatings was demonstrated to reinforce to a different extent
the barrier characteristics of composite coatings, consequently, possibly prolonging their durability in a 3 % NaCl
solution. Moreover, a thorough investigation into the varying inhibition patterns displayed by bifunctional REcomplexes
is clarified via theoretical computations. Predictions derived from density functional theory/molecular
dynamics simulations indicate the possible development of various inhibitory compounds within the electrolyte.
The corrosion inhibition mechanism hypothesized for RE-thioglycolates is based on both electrochemical and
theoretical understandings, further corroborated through surface analysis techniques. Although significant, the RE
loading within a coating does not singularly dictate the corrosion stability of composite coatings. The protective
properties and self-healing capability were discovered also to result from an intricate interplay among the type of
rare earth, its origin, solubility within the composite coating, and surface morphology.

AB  - Since 2000. onward, a benefit of self-healing ability has been often imposed on the new generation
coatings, particularly for those aiming for corrosion protection. It is expected for the coating to self-repair
the spots damaged by some mechanical or chemical interaction in corrosion environment by some
internal chemical process. Polymers or polymer-containing composites, coatings with micro and
nanocapsules and hybrid oxide coatings have been reported as the most successfully utilized self-healing
coating materials [1-3].
The rare earth elements (RE) incorporated in the coating diffuse to the damaged spot on the substrate, and
in the reaction with the environment form insoluble oxides/hydroxides, resembling the behavior of
conversion coating containing Cr(VI) compound. A new route for producing coating materials has
emerged in the last ten years, whereby RE is incorporated in the metal coating matrix instead of utilizing
it within the top conversion coating. This way RE could be dissolved during electrolyte penetration
through the coating and easily available for self-healing action.
Having this in mind the aim of the research was probing the corrosion resistance of Zn and Zn-Co alloy
coating, by the incorporation of Ce ion via the electrodeposition process. The influence of CeO2, CeCl3
and Ce-thioglycolate as an additional alloying element besides Co, on the morphology and corrosion
performance of the Zn-Co-Ce electrodeposited coatings, was investigated by scanning electron
microscopy coupled with energy dispersive X-ray spectroscopy and electrochemical impedance
spectroscopy measurements. The Zn-composite coatings were assessed for comparison. The percentages
of Ce in the coating could be very finely tuned by setting electrodeposition parameters, including cathodic
current density, type of electrolyte agitation and the source of Ce. Cerium was incorporated in the
coatings through the mechanism of oxide/hydroxide formation during the electroreduction of Zn and Co.
Corrosion resistance of the composite coatings was enhanced compared to Zn and binary Zn-Co, as
demonstrated by electrochemical impedance spectroscopy and scanning Kelvin probe results. The Ceoxides
inclusion was verified by XRD as the crystalline phase. The beneficial effect of utilizing CeCl3, as
opposed to CeO2 and Ce-thioglycolate in electrodeposition of composite coatings was shown and
discussed.

AB  - The aim of this study is development and characterization of the novel Zn-Mn/Al2O3 composite coatings. The coatings 
were electrodeposited with constant current density on steel, from chloride solution, without any commercial additives. The 
Zn−Mn alloy coatings that show high corrosion resistance, may be used in future as an alternative to cadmium coatings. 
However, the pure Zn and Zn alloy coatings are characterized with poor mechanical properties. Therefore, in this work the 
alumina particles were incorporated into the Zn-Mn matrix, and the hardness and corrosion resistance of the obtained 
composite coatings were tested. The mechanical and ultrasound agitation were used to achieve good dispersion of plating 
solution and homogeneous co-deposition of second phase. The goal was to examine the effect of the agitation type in bath, 
on the attributes of the deposited composite coatings. The incorporation of Al2O3 particles was enhanced when the 
mechanical agitation of the solution was applied. However, in case that this agitation method was used, the agglomeration of 
the alumina particles occurred. In contrast, when an ultrasonic agitation of the plating solution was applied, the uniform 
distribution of the alumina particles could be achieved. The presence of particles in the matrix, along with applied 
ultrasound, resulted in grain refinement and homogeneous microstructure. The Al2O3 nanoparticles incorporated in Zn-Mn 
alloy matrix, resulted in a significant increment in the indentation hardness and a modest increase in the coating corrosion 
resistance. However, the coating hardness increased with alumina addition, only in case when an ultrasonic agitation of the 
electrodeposition solution was used.

AB  - Aim of this work was to determine influence of current density on the roughness of the
electrodeposited zinc coatings. Electrodeposition carried out from two same solutions containing
different brightening additives. Furfural (in solution I) and dextrin (in solution II) were used as
additives. Influences of the thickness of the coatings on the surface roughness depending of the
current density and time of deposition and effect of the added additives on the structure of the coatings
were also studied.
Electrodeposition of the zinc coatings was done galvanostatically at current densities of 1, 2 and 4 A
dm-2. Times of electrodeposition were 10, 20 and 30 minutes. Pure zinc was used as anode, and steel
with unknown composition was used as cathode. All experiments were done at room temperature,
baths volume were 500 cm3.
Obtained results show that zinc coatings obtained from solution II have lower roughness than those
deposited from solution I. Current density and thickness of the coatings does not have large influence
on the roughness. The roughness values are from 0.41 μm to 1.219 μm (solution I) and from 0.316
μm to 0.812 μm (solution II). Current efficiency in solution I is 92.98-94.55% and in solution II 91.5-
96.91%. Coatings from solution II have better structure compared to coatings obtained from solution
I, so it can be concluded that dextrin is better brightening additive than furfural in used sulphate
baths.

AB  - In this paper chemical and electrochemical treatment of aluminium and measurement of roughness were carried out. Before chemical or electrochemical treatment of aluminium samples chemical preparation is done to remove oxide coating on surface. Three solutions are used for chemical and two solutions for electrochemical treatment. All used solutions give good results, because after chemical and electrochemical treatment the roughness of surface is decrease for all samples. It is shown by measurements of surface roughness. The surface of aluminium has specific color and visual appearance after treatments. Because of various colours, aluminium can be used in different enterer or exterior, depending of the needs of the market. Some of used solutions are commercial, which is used in d.o.o “Alpro” Vlasenica. Increase of time of treatments leads to decrease of the roughness of surface. The best results were obtained in solutions (H1) and (H2) of all used solutions for chemical and electrochemical treatments of aluminium surface. The samples of aluminium treated in solutions (H1) and (H2) have lower roughness of surface and its value is 0,235-0,268µm. The most intense color is obtained during treatment of samples in solutions (H1) and (H2), i.e. by chemical treatment of aluminium samples.
AB  - U ovom radu je vršena hemijska i elektrohemijska obrada aluminijuma, nakon čega je merena hrapavost uzoraka. Pre hemijske ili elektrohemijske obrade uzoraka aluminijuma potrebno je izvršiti hemijsku pripremu i ukloniti zaštitnu oksidnu opnu. Za hemijsku obradu korišćena su tri, a za elektrohemijsku obradu dva rastvora. Svih pet korišćenih rastvora daju dobre rezultate, jer nakon hemijske i elektrohemijske obrade dolazi do smanjenja površinske hrapavosti. To pokazuju izvršena merenja površinske hrapavosti svih uzoraka. Takođe, nakon tretmana u svakom od rastvora dobija se i specifična boja i različit vizuelni izgled površine aluminijuma. U zavisnosti od boje, aluminijum se može uklapati u različite enterijere i eksterijere u zavisnosti od zahteva tržišta. Neki od korišćenih rastvora su komercijalni rastvori koji se već koriste u d.o.o „Alpro“ Vlasenica. Sa povećanjem vremena obrade dolazi do smanjenja hrapavosti uzoraka aluminijuma. Od pet korišćenih rastvora za hemijsko i elektrohemijsko bojenje aluminijuma, najbolje rezultate pokazali su rastvori (H1) i (H2). Uzorci aluminijuma obrađeni u ovim rastvorima imaju najmanju hrapavosti i ona se kreće od 0,235-0,268µm. Najintezivnija boja je dobijena prilikom obrade uzoraka u rastvoru (H1) i (H2)tj. pri hemijskoj obradi uzoraka aluminijuma.

AB  - Zbog sve veće brige stručne i naučne javnosti o zaštiti životne sredine došlo je do upotrebe ekološki prihvatljivih inhibitora za zaštitu metala od korozije. U ovom radu izvršeno je ispitivanje zaštite bakra obradom korozione sredine primenom različitih koncentracija ekstrakta žalfije 0.5g/dm3,1 g/dm3 i 1.5g/dm3, kao zelenog inhibitora, u rastvoru 3% NaCl. Merenja su izvedena gravimetrijskom metodom i elektrohemijskim metodama (Tafelovom metodom ekstrapolacije i spektroskopijom elektrohemijske impedanse). Najveće dostignute vrednosti zaštitnog faktora ekstrakta žalfije su 60,04% u rastvoru 3%NaCl + 1 g/dm3 i 53% u rastvoru 3%NaCl + 1,5 g/dm3 u vremenskom intervalu od 6 sati. Međutim, isti rastvori u vremenskom intervalu od 4 i 24 h deluju katalitički na proces korozije bakra, te se ekstrakt žalfije ne može preporučiti kao inhibitor korozije bakra u 3%NaCl. Rezultati dobijeni spektroskopijom elektrohemijske impedanse i rezultati dobijeni sa snimljenih Tafelovih polarizacionih dijagrama potvrđuju rezultate dobijene gravimetrijskom metodom, te se mogu preporučiti kao vrlo pouzdane metode za brza koroziona ispitivanja.

In this paper, research on copper protection by processing corrosive environment while applying different concentrations of sage extract of 0.5g/dm3,1 g/dm3 i 1.5g/dm3 as green inhibitor in 3% NaCl solution was performed. Measurements were carried out by gravimetric method and electrochemical methods (Tafel extrapolation method and electrochemical impedance spectroscopy). The greatest protective values of sage extract of 60,04% were reached in 3%NaCl + 1 g/dm3 solution and 53% 3%NaCl + 1,5 g/dm3 solution in 6 hours interval. However, the same solutions act catalytically on copper corrosion process during time interval from 4 to 24 hours, that is why sage extract can not be recommended as inhibitor of copper corrosion in 3%NaCl. The results obtained by electrochemical impedance spectroscopy and recorded Tafel polarization diagrams, confirm results attained by gravimetric method, thus can be recommended as very reliable methods for quick corrosion tests.

AB  - In this paper the research of corrosion protection of steel by processing corrosion environment using various concentrations of sage extracts (Salvia officinalis) (0.5 g/dm(3), 1 g/dm(3) and 1.5 g/dm(3)) in a 4% solution of HCl was carried out. Measurements were performed using gravimetric and electrochemical methods (Tafel extrapolation method and electrochemical impedance spectroscopy). The results have showed that sage is recommendable as a possible inhibitor in 4% solutions of HCl. The research also confirms that electrochemical impedance spectroscopy is a reliable method to use for rapid corrosion tests, since the results confirm the gravimetric measurements of corrosion indicators. Determination of corrosion rate and the degree of protection using Tafel diagrams calculated on the basis of corrosion current did not give reliable results. The results show that sage may be used as a "green inhibitor" for protection of steel in a shorter period of time. The degree of protection ranges up to 64.5% for steel 2; however, since sage is environmentally friendly, it is a suitable corrosion inhibitor for shorter periods of time.

AB  - The potentiostatic method and the theory of 'topochemical reactions' in the kinetics of the active dissolution and passivation process of AISI 420 stainless steel were studied. It was found that, to a great extent, the number of conversion steps is depended on the imposed potential. The experimentally obtained results were partially explained using Okamoto's theory of passivation.

AB  - Electrochemically deposited Zn-Ni-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy for the determination of the chemical composition, atomic force microscopy for surface morphology analysis, and electrochemical impedance spectroscopy for determination of corrosion properties. The influence of the ratio of the alloying elements, [Co2+]/[Ni2+], in a chloride deposition solution, as well as the deposition current density, on the chemical content, morphology and corrosion properties of the ternary alloys was studied. The plating solutions used were with the same overall metal concentration, free of additives and the deposition was realized at room temperature. It was shown that the deposition of the ternary alloy coatings was of anomalous type and that the ratio of nickel to cobalt ions in the plating solution, as well as the deposition current density, had a significant influence on the chemical composition and corrosion stability of these coatings. The presence of both Ni and Co was beneficial for their corrosion stability. It was shown that morphology and porosity were important factors in the corrosion stability of these coatings. The coating deposited from the solution with higher [Co2+]/[Ni2+] ratio at 8 A dm(-2) was made up of the smallest crystalline aggregates, had a small surface roughness and porosity, and was with quite uniform distribution of agglomerates and it exhibited the best corrosion stability.

AB  - The subject of the research is influence of sulfuric acid on morphology of electrochemically obtained copper powder during galvanostatic electrolysis mode. In this paper electrodeposition of copper powder from sulphate electrolyte was carried out. Electrolytes with three different concentrations of Cu2+ (7 g/dm3, 18 g/dm3 and 33 g/dm3) were used, each in combination with three different concentrations of H2SO4 (100 g/dm3, 150 g/dm3 and 200 g/dm3), so that copper powder was deposited from nine electrolytes. Copper wire with surface area of 1cm2 was used as cathode, and copper anode in the form of metal sheet was pressed against the wall of electrochemical cell that had volume of 500 cm³. Experiments were carried out at room temperature, and electrolyte stirring was performed using a magnetic stirrer. Copper powder was deposited galvanostatically at current densities of j = 1500 A/m2, j=2000 A/m2 and j=2500 A/m2. Produced copper powder was removed from cathode every three minutes. All the characteristics of powder depend on the size and shape (morphology) of particles and they are mutually correlated. Research of morphology and size of particle was carried out using scanning electron microscopy (SEM). Increase of H2SO4 concentration causes increase in branching of copper powder. It was concluded that the size of copper powder grains reduces with the increase in concentration of H2SO4.

Kao katoda je korišćena bakarna žica površine 1cm2, a bakarna anoda u obliku lima je bila priljubljena uz zid elektrohemijske ćelije, zapremine 500 cm³. Eksperimenti su izvođeni na sobnoj temperaturi, a mešanje elektrolita vršeno je pomoću magnetne mešalice. Bakarni prah taložen je galvanostatski pri gustinama struje od: j=1500 A/m2, j=2000 A/m2 i j=2500 A/m2. Proizvedeni bakarni prah je uklanjan sa katode svaka tri minuta. Sve osobine praha zavise od oblika i dimenzija čestica (morfologije) i međusobno su povezane. Ispitivanje morfologije i veličine čestica vršeno je pomoću skenirajuće elektronske mikroskopije (SEM). Sa povećanjem koncentracije H2SO4, povećava se i razgranatost bakarnog praha. Utvrđeno je da se veličina čestica smanjuje sa povećanjem koncentracije H2SO4.

AB  - The inhibitive behaviour of Vitamin C, as a type of green inhibitor, on the corrosive behaviour of stainless-steel (SS) X4Cr13 within an aqueous solution of hydrochloric acid (HCl) was studied at concentration of c= (0.01, 0.1 and 1.0) mol L-1. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS), was used for the measurements at 25 degrees C. To observe the morphology and microstructures of sample surfaces, after the electrochemical measurements a Scanning electron microscopy (SEM) was used. On the basis of the EDAX analysis within the solution of hydrochloric acid (0.01 mol L-1) with addition of Vitamin-C (0.005 mol L-1) the presence of the feri-chelates on the metal surface could be confirmed. The polarization curves revealed that the studied mixtures of the chosen inhibitor represented mixed-type of the inhibitor. The results show that the inhibition efficiency increases with the increase of the inhibitor concentration. This valid especially in the case of the lowest concentration of HCl (c= 0.01 mol L-1). In addition to this at higher HCl concentration (c= 1.0 mol L-1) the immersion time has a noticeable influence on the inhibitive response. Furthermore, the results obtained in this study showed that the inhibitory effect of Vitamin-C to a great extent on electrode potential.

AB  - Ispitivana je električna provodljivost sistema baziranog na lignoceluloznom (LC) biopolimernom matriksu ispunjenog elektrohemijski dobijenim bakarnim prahom. Galvanostatski dobijen bakarni prah sa veoma poroznim, veoma dendritičnim i česticama sa velikom specifičnom površinom je korišćen kao punilac. Zapreminski udeo elektrohemijski dobijenog bakarnog praha je iznosio od 2.0 - 29.8 vol%.

AB  - The electrical conductivity of the composite system based on lignocellulose (LC) biopolymer matrix electrodeposited copper powder filler has been studied. Highly porous, highly dendritic galvanostatically produced copper powder was used as filler since these particles have high values of specific area. Volume fraction of the electrodeposited copper powder was varied from 1.9 - 29.4 vol%. Analysis of the most significant properties of prepared composites and its components included impedance spectroscopy (IS) behavior, measurements of electrical conductivity, scanning electron microscopy (SEM) and structural analysis. The significant increase of the electrical conductivity could be observed as the copper powder content reaches the percolation threshold (PT). It was shown that PT depends on both particle shape and type of spatial distribution. IS measurements and SEM analysis have shown that particles having pronounced grain boundaries have great effect on appearance of electric conductive pathways thus on the composite conductivity. The packaging effect and more pronounced interpartical contact with copper powder particles lead to “movement” of PT, which for the particles <45 μm and highest processing pressure of 27 MPa was 7.2% (v/v). IS response of the composites showed existence of electrical 
conductive layers, each having different resistivity which increases towards interior of the composite.

AB  - U radu je ispitivan uticaj gustine struje na morfologiju elektrohemijski dobijenog bakarnog praha. 
Vršeno elektrohemijsko taloženje bakarnog praha iz sulfatnih elektrolita. Korišćeni su elektroliti sa tri koncentracije Cu2+ ( 7 g/dm3, 18 g/dm3 i 33 g/dm3 i svaka u kombinaciji sa tri koncentracije H2SO4 (100 g/dm3, 150 g/dm3 i 200 g/dm3), tako da je bakarni prah taložen iz devet elektrolita. Kao katoda je korišćena bakarna žica površine 1cm2, a bakarna anoda je bila priljubljena uz zid elektrohemijske laboratorijske ćelije zapremine 500cm³. Eksperimenti su rađeni na sobnoj temperaturi, a cirkulacija elektrolita vršena je pomoću magnetne mešalice. Bakarni prah taložen je galvanostatski pri gustinama struje od: j=1500A/m2, j=2000A/m2 i j=2500A/m2. Proizvedeni bakarni prah sa katode otresan je svakih tri minuta. Sve osobine praha zavise od oblika i dimenzije čestice (morfologije), od kojih je prah sačinjen i međusobno su povezane. Ispitivanje morfologije i veličine čestice vršeno je pomoću skenirajuće elektronske mikroskopije (SEM). Analizom dobijenih mikrofotografija utvrđeno je da se sa povećanjem gustine stuje morfologija čestica bakarnog praha menja od kompaktnih, masivnih dendrita i masivnih čestica, do razgranatih, 3D dendrita koji imaju strukturu kao zrna kukuruza.

AB  - The paper investigates the effect of current density on the morphology of copper powder obtained 
electrochemically. Copper powder from sulphate electrolytes was deposited electrochemically. The 
electrolytes used had three different concentrations of Cu2+ ( 7 g/dm3, 18 g/dm3 and 33 g/dm3) each combined with three concentations of H2SO4 (100 g/dm3, 150 g/dm3 and 200 g/dm3), so that copper powder was deposited from nine electrolytes. The cathode was a copper wire with the surface of 1cm2, whereas the copper anode was attached to the wall of the electrochemical laboratory cell with the volume of 500cm³. The experiments were performed at room temperature and the circulation of electrolytes was conducted using a magnetic stirrer. Copper powder was deposited galvanostatically at the following current densities: j=1500A/m2, j=2000A/m2 and j=2500A/m2. The copper powder produced was shaken off from the cathode every three minutes. All the properties of the powder depend on the shape and size of the particles (morphology) which constitute the powder and they are in correlation. Investigation of the morphology of particles was performed using scanning electron microscopy (SEM). The analysis of the obtained microphotographs shows that the increase of current density changes the morphology of copper powder particles from compact, massive dendrites and massive particles to branching 3D dendrites with the straucture of corn grains. The increase in current density results in smaller 
particles of copper powder which are evenly distributed.

AB  - The electrochemical deposition by pulse current of Zn-Co alloy coatings on steel was examined, with the aim to find out whether pulse plating could produce alloys that could offer a better corrosion protection. The influence of on-time and the average current density on the cathodic current efficiency, coating morphology, surface roughness and corrosion stability in 3% NaCl was examined. At the same Ton/Toff ratio the current efficiency was insignificantly smaller for deposition at higher average current density. It was shown that, depending on the on-time, pulse plating could produce more homogenous alloy coatings with finer morphology, as compared to deposits obtained by direct current. The surface roughness was the greatest for Zn-Co alloy coatings deposited with direct current, as compared with alloy coatings deposited with pulse current, for both examined average current densities. It was also shown that Zn-Co alloy coatings deposited by pulse current could increase the corrosion stability of Zn-Co alloy coatings on steel. Namely, alloy coatings deposited with pulse current showed higher corrosion stability, as compared with alloy coatings deposited with direct current, for almost all examined cathodic times, Ton. Alloy coatings deposited at higher average current density showed greater corrosion stability as compared with coatings deposited by pulse current at smaller average current density. It was shown that deposits obtained with pulse current and cathodic time of 10 ms had the poorest corrosion stability, for both investigated average deposition current density. Among all investigated alloy coatings the highest corrosion stability was obtained for Zn-Co alloy coatings deposited with pulsed current at higher average current density (jav = 4 A dm-2).
AB  - Ispitivano je elektrohemijsko taloženje cink-kobalt legure pulsirajućom strujom na čeliku, a s ciljem dobijanja zaštitnih prevlaka sa povećanom korozionom stabilnošću. Prevlake legura su taložene pulsirajućim režimom sa različitim srednjim gustinama struje i pri različitom trajanju katodnog pulsa. Analiziran je uticaj ovih parametara na iskorišćenje struje prilikom elektrohemijskog taloženja na izgled prevlaka (snimanje elektronskim mikroskopom), hrapavost prevlaka i njihovu korozionu stabilnost u 3% NaCl (merenjem slobodnog korozionog potencijala u agensu korozije i snimanjem polarizacionih krivih). Pokazano je da u zavisnosti od vremena pulsa, prevlake taložene pulsirajućim režimom mogu da imaju bolju homogenost, sitnije aglomerate kristalnih zrna i manju hrapavost od onih taloženih pri istim uslovima, ali konstantnom gustinom struje. Veću korozionu stabilnost pokazale su prevlake legura taložene većom srednjom gustinom struje.

Among all investigated alloy coatings the highest corrosion stability was obtained for Zn-Co alloy coatings deposited with pulsed current at higher average current density (jav = 4 A dm-2)., Ispitivano je elektrohemijsko taloženje cink-kobalt legure pulsirajućom strujom na čeliku, a s ciljem dobijanja zaštitnih prevlaka sa povećanom korozionom stabilnošću. Prevlake legura su taložene pulsirajućim režimom sa različitim srednjim gustinama struje i pri različitom trajanju katodnog pulsa. Analiziran je uticaj ovih parametara na iskorišćenje struje prilikom elektrohemijskog taloženja na izgled prevlaka (snimanje elektronskim mikroskopom), hrapavost prevlaka i njihovu korozionu stabilnost u 3% NaCl (merenjem slobodnog korozionog potencijala u agensu korozije i snimanjem polarizacionih krivih). Pokazano je da u zavisnosti od vremena pulsa, prevlake taložene pulsirajućim režimom mogu da imaju bolju homogenost, sitnije aglomerate kristalnih zrna i manju hrapavost od onih taloženih pri istim uslovima, ali konstantnom gustinom struje. Veću korozionu stabilnost pokazale su prevlake legura taložene većom srednjom gustinom struje.",

AB  - The electrical conductivity of the system based on lignocellulose (LC) biopolymer matrix filled with electrodeposited copper powder has been studied. Galvanostatically produced copper powder, having highly porous, highly dendritic particles with high values of specific area was used as filler. Volume fraction of the electrodeposited copper powder was varied from 2.0-29.8 vol%. Analysis of the most significant properties of prepared composites and its components included measurements of electrical conductivity, impedance spectroscopy (IS) behavior, structural and morphological analysis. The composite preparation conditions allowed the formation of a random distribution of metallic particles in the polymer matrix volume. It was shown that percolation threshold depends on both particle shape and type of spatial distribution. IS measurements have shown that particle morphology having pronounced grain boundaries has great effect on appearance of electric conductive layers, i.e.. movement. of percolation threshold towards lower filler volume fractions. IS response of the composites showed existence of electrical conductive layers, each having different resistivity which increases towards interior of the composite.

AB  - The first successful attempt to electrodeposit Zn-Mn alloy coatings from alkaline bath was made only a few years ago. In this kind of solution, potassium pyrophosphate (K4P2O7) serves both as a complexing agent and as the basic electrolyte. The aim of this work was to study the electrodeposition process and properties of Zn-Mn alloy coatings deposited from pyrophosphate solution, with a new kind of alkaline pyrophosphate bath. Namely, chloride salts were used as the source of metal ions and ascorbic acid was used as reducing agent. The composition of the plating solution was as follows: 1 mol dm-3 K4P2O7 + 0.017 mol dm-3 ascorbic acid + 0.05 mol dm-3 ZnCl2 + 0.05 mol dm-3 MnCl2·4H2O. Cathodic processes during the alloy electrodeposition were investigated using linear voltammetry. The influence of addition of small amounts of ascorbic acid on the cathodic processes was established. It was shown that this substance inhibits hydrogen evolution and increases the current efficiency of alloy deposition. The current efficiency in the plating bath examined was in the range of 25 and 30%, which was quite higher as compared to the results reported in the literature for electrodeposition of Zn-Mn alloy from pyrophosphate bath. Electrodeposition of Zn-Mn alloys was performed galvanostatically on steel panels, at current densities of 20?120 mA cm-2. The coatings with the best appearance were obtained at current densities between 30 and 80 mA cm-2. The surface morphology studies, based on atomic force microscopy measurements, showed that morphology of the deposits is highly influenced by deposition current density. Zn-Mn coating deposited at 30 mA cm-2 was more compact and possessed more homogeneous structure (more uniform agglomeration size) than the coating deposited at 80 mA cm-2. Such dependence of morphology on the current density could be explained by the high rate of hydrogen evolution reaction during the electrodeposition process.

AB  - The effect of different deposition regimes (constant and reversing currents, constant and pulsating overpotential), on the powdered and dendritic silver electrodeposits morphology were investigated. The morphology of electrodeposited silver powder was studied utilizing a scanning electron microscope. The results obtained in constant regimes were compared with those obtained in pulsating and reversing regimes. The size of dendrites decreased strongly with increased overpotential or current. It was also shown that the agglomeration of silver dendrites in spongy-like agglomerates was strongly decreased by pulsating overpotential electrodeposition or reversing current. The possibility of obtaininig powder particles, with different properties, depending on conditions of electrolysis was demonstrated.

AB  - This paper analyzes the catalytic effect of sulphuric acid on current efficiency, the coating thickness and the rate of deposition of electrochemical chromium coatings. According to the properties of chrome, there are three types of chrome coatings: decorative, hard and porous. The quantitative composition of baths and working conditions are the factors which determine which type of a coating will be obtained. The cathodes are made of copper electrolitical plates (99.99%), which are submitted to mechanical smoothing and chemical preparation. Electrochemical chromium coatings were deposited galvanostaticaly from bath I (250 g/dm3 CrO3 + 2.0 g/dm3 H2SO4), are then deposited on the cathodes prepared in this way, also from bath II (250 g/dm3 CrO3 + 2.5 g/dm3 H2SO4), and from bath III (250 g/dm3 CrO3 + 3.0 g/dm3 H2SO4), at current densities of 10 A/dm2, 15 A/dm2 and 30 A/dm2. Deposition was performed for 5, 10 and 15 minutes intervals in all three baths and for all three current densities. The difference in samples mass before and after electrochemical deposition was measured on the analytical scale. Cathodic current efficiency, the coating thickness and deposition rate increase with the increase of acid concentration, current density and deposition time. The average deposition rates are approximately the same for baths II and III, for the same deposition time, at the same current densities. This shows that the increase of the concentration of sulphuric acid above 2.5 g/dm3 is not justifiable. The ratio of these parametres, according to the quantity of the sulphuric acid used is the best for bath II, which makes deposition of electrochemical chrome coatings from this bath most profitable, from the aspect of current efficiency, deposition rate, coatings quality and chemicals consumption of bath.
AB  - Ispitivan je katalitički uticaj sumporne kiseline na iskorišćenje struje, debljinu i brzinu taloženja prevlaka hroma dobijenih elektrohemijskim putem. Zahvaljujući osobinama hroma razlikuju se tri vrste prevlaka: dekorativne, tvrde i porozne. Kvantitativni sastav kupatila i radni uslovi su faktori koji određuju koji tip prevlaka će biti dobijen. Katode su bile od tehničkog bakra nepoznatog sastava, koje su mehanički glačane pa zatim hemijski pripremljene. Za elektrohemijsko taloženje prevlaka hroma, koje su taložene galvanostatski, ispitivana su tri elektrolita čiji se kvantitativni sastav razlikuje u koncentraciji sumporne kiseline, dok je koncentracija CrO3 bila ista u sva tri kupatila i to: kupatilo I (250 g/dm3 CrO3 + 2.0 g/dm3 H2SO4), zatim kupatilo II (250 g/dm3 CrO3 + 2.5 g/dm3 H2SO4), i na kraju kupatilo III (250 g/dm3 CrO3 + 3.0 g/dm3 H2SO4), pri gustinama struje 10 A/dm2, 15 A/dm2 i 30 A/dm2. Katodno iskorišćenje struje, debljina prevlaka i brzina taloženja se povećava sa povećanjem koncentracije sumporne kiseline, gustine struje taloženja i vremena taloženja. Srednje brzine taloženja prevlaka hroma su približno iste za kupatila II i III, pri istim vremenima taloženja i pri istim gustinama struje. S tim u vezi, povećanje koncentracije sumporne kiseline iznad 2,5 g/dm3 nije opravdano. Odnos ovih parametara, prema koncentraciji sumporne kiseline, je najbolji za kupatiko II, koje daje optimalne prevlake hroma dobijene elektrohemijskim putem, u pogledu iskorišćenja struje, brzine taloženja, kvalitata prevlake i hemijskog sastava kupatila.

abstract = "This paper analyzes the catalytic effect of sulphuric acid on current efficiency, the coating thickness and the rate of deposition of electrochemical chromium coatings. According to the properties of chrome, there are three types of chrome coatings: decorative, hard and porous. The quantitative composition of baths and working conditions are the factors which determine which type of a coating will be obtained. The cathodes are made of copper electrolitical plates (99.99%), which are submitted to mechanical smoothing and chemical preparation. Electrochemical chromium coatings were deposited galvanostaticaly from bath I (250 g/dm3 CrO3 + 2.0 g/dm3 H2SO4), are then deposited on the cathodes prepared in this way, also from bath II (250 g/dm3 CrO3 + 2.5 g/dm3 H2SO4), and from bath III (250 g/dm3 CrO3 + 3.0 g/dm3 H2SO4), at current densities of 10 A/dm2, 15 A/dm2 and 30 A/dm2. Deposition was performed for 5, 10 and 15 minutes intervals in all three baths and for all three current densities. The difference in samples mass before and after electrochemical deposition was measured on the analytical scale. Cathodic current efficiency, the coating thickness and deposition rate increase with the increase of acid concentration, current density and deposition time. The average deposition rates are approximately the same for baths II and III, for the same deposition time, at the same current densities. This shows that the increase of the concentration of sulphuric acid above 2.5 g/dm3 is not justifiable. The ratio of these parametres, according to the quantity of the sulphuric acid used is the best for bath II, which makes deposition of electrochemical chrome coatings from this bath most profitable, from the aspect of current efficiency, deposition rate, coatings quality and chemicals consumption of bath., Ispitivan je katalitički uticaj sumporne kiseline na iskorišćenje struje, debljinu i brzinu taloženja prevlaka hroma dobijenih elektrohemijskim putem. Zahvaljujući osobinama hroma razlikuju se tri vrste prevlaka: dekorativne, tvrde i porozne. Kvantitativni sastav kupatila i radni uslovi su faktori koji određuju koji tip prevlaka će biti dobijen. Katode su bile od tehničkog bakra nepoznatog sastava, koje su mehanički glačane pa zatim hemijski pripremljene. Za elektrohemijsko taloženje prevlaka hroma, koje su taložene galvanostatski, ispitivana su tri elektrolita čiji se kvantitativni sastav razlikuje u koncentraciji sumporne kiseline, dok je koncentracija CrO3 bila ista u sva tri kupatila i to: kupatilo I (250 g/dm3 CrO3 + 2.0 g/dm3 H2SO4), zatim kupatilo II (250 g/dm3 CrO3 + 2.5 g/dm3 H2SO4), i na kraju kupatilo III (250 g/dm3 CrO3 + 3.0 g/dm3 H2SO4), pri gustinama struje 10 A/dm2, 15 A/dm2 i 30 A/dm2. Katodno iskorišćenje struje, debljina prevlaka i brzina taloženja se povećava sa povećanjem koncentracije sumporne kiseline, gustine struje taloženja i vremena taloženja. Srednje brzine taloženja prevlaka hroma su približno iste za kupatila II i III, pri istim vremenima taloženja i pri istim gustinama struje.

AB  - Fizičke i hemijske karakteristike metala određuju njegovo elektrohemijsko ponašanje. Gvožđe, prema elektrohemijskoj klasifikaciji metala, spada u grupu prelaznih metala. Ono pripada grupi "inertnih metala", sa malom gustinom struje izmene j0, i visokom elektrohemijskom prenapetošću taloženja, η i njegovo taloženje je praćeno izdvajanjem vodonika. Elektrohemijskim taloženjem metala nastaju različiti nepravilni morofološki oblici taloga, kao što su: dendriti, igle, sunđeri, vlaknaste strukture, strukture pčelinjeg saća itd. Ovakve morfološke forme su ili korisne ili neželjene. U ovom radu su ispitivane polarizacione karakteristike elektrohemijskog procesa taloženja praha gvožđa, iz sulfatnih i hloridnih elektrolita, kao i njihova morfologija. Analiza morfologije i karakterizacija dobijenih prahova, vršena je pomoću SEM i EDS. Utvrđeno je da morfologija čestica zavisi od vrste anjona prisutnih u elektrolitu, ali ne i od primenjene gustine struje u ispitivanom opsegu. Čestice istaložene iz sulfatnih elektrolita, su pretežno dendritične sa karfiolastim, kristaličnim završecima i da poseduju kupaste šupljine. Kod Fe prahova istaloženih iz hloridnih elektrolita, uočeni su aglomerati, a takođe su prisutne šupljine zbog intenzivnog izdvajanja vodonika.
AB  - Various irregular morphological forms of metal deposits, such as dendrite, needle, spongy, fibrous, honeycomb-like structure, etc., can be formed by electrodeposition processes. These forms may be either useful or undesirable. According to electrochemical classification of metals, the transition metals such as Fe, belong to the "inert metal", with small exchange current density j0 and high overpotential of electrodeposition η. In this work the polarization characteristics of electrodeposition processes of Fe powders from sulfate and chloride electrolytes and their morphology were investigated. The morphology and characterization of the electrodeposited powders were investigated by SEM and EDS analysis. The morphology of obtained powders depends on the anion presence in the electrolyte, but not on the current density in investigated range. Characteristic feature of dendritic powder with cauliflower endings obtained from sulfate electrolyte is the presence cone-like type of cavities and crystallite morphology of the powders surface. Fe powders electrodeposited from chloride electrolyte appear in form of agglomerates.

AB  - Iron deposits obtained at high current densities and overpotentials are very important from a technological point of view. It has been stated that the open and porous structures of copper or iron deposits obtained at high current densities were ideally suited for use as electrodes in electrochemical devices such as fuel cells, batteries and chemical sensors, while the extremely high surface area is relevant for evaluating some electrochemical reactions. Mainly two types of electrolytes were investigated and these were based on sulfate and chloride electrolytes. With increasing duration of electrolysis, dendrites merge, which is unacceptable for the case of further application. These deposits must be grinded in order to obtain powders. However, in the range of lower acidity the deposits become powdery and, in some cases, may be spongy and sticky. Generally, up to now research indicates that electrodeposition of Fe powders have two steps, deposition of fragile film and grinding. It must be emphasized that we tried and succeeded to obtain Fe powders without grinding process. The aim of this work was to investigate electrodeposition processes of Fe powders from sulfate and chloride electrolytes and morphologies of powder as a function of type of electrolyte and current density.
