AB  - Monitoring the occurrence and rate of corrosion, the formation of thermal oxides on the surface of metal parts of the power plant, as well as the method of their elimination in a way that is technologically suitable, economically affordable and environmentally justified is shown in this technical solution. It has been established that the metal elements affected by corrosion were made from stainless steel AISI 304. Accordingly, the occurrence of corrosion and thermal oxides was monitored based on the material and the composition of the dust with which the metal parts are in contact. The emergence of thermal oxides on the surface of stainless steels is a consequence of the elevated temperature at the welding site.The pH value of both solutions was measured: standard and saturated solution of dust from the plant. The composition of the dust samples was determined by FTIR. The other tests were defined based on the ions present in the solution.The corrosion potential, the value of the polarization resistance, as well as the corrosion current density were determined. All tests of stainless steel in the standard solution and in the saturated solution of dust were performed for one hour within a span of 25 days.Technological recommendations on how to eliminate corrosion and thermal oxides are provided.The solution has been applied since January 2021 by ELNOS BL d.o.o.

AB  - Poly(aniline-co-(m-aminobenzoic acid)) was synthesized electrochemically at graphite electrode under galvanostatic conditions. Aqueous electrolyte for synthesis was consisted of HCl and different amount of aniline and m-aminobenzoic acid. The presence of the meta positioned carboxylic group in m-aminobenzoic acid influenced higher co-polymerization potential, different morphology and electrochemical behavior of copolymers compared to polyaniline. Electrochemical activity is achieved by proton exchange in neutral environment that can result in a faster charge/discharge process, which is in the case of PANI limited by slow anion exchange, making this material promising for consideration in super-capacitors and in biological system.

AB  - Ceria coating is formed on Al from the ceria sol prepared exclusively by forced hydrolysis of Ce(NO3)(4), in order to test their ability to protect Al from corrosion. The characterization of sol-gel-processed ceria coating and coating/Al assembly brings new issues on Al corrosion and protection caused by unique properties of the sol-gel coating. The corrosion behaviour of bare Al and Al/CeO2 is investigated by the electrochemical impedance spectroscopy (EIS) during the exposure to NaCl aqueous solution. The morphology and composition of the samples are examined by scanning electron microscopy and energy dispersive spectroscopy. EIS data showed greater corrosion resistance of CeO2-coated aluminium in comparison to bare Al at long exposure times. CeO2 coating does not hinder completely the corrosion processes on Al. The Al beneath CeO2 coating is subjected to intrinsic formation of a uniform protective coating/Al interphase, cross-linked by AlO(OH) fibre-like structures. They appear created by corrosive medium from the coating reversely gelled by NaCl solution. As the fibre network is created during exposure, Al becomes better protected than by spontaneous formation of porous passive layer of Al(OH)(3) on bare aluminium. Sol-gel ceria coatings thus improve corrosion resistance of aluminium during prolonged exposure to corrosive medium.

AB  - The simulated shapes of the polarization curves were correlated with the type of metal electrodeposition process control as a function of the ratio of the exchange current density to the limiting diffusion current density (j(0)/j(L)). Diagnostic criteria based on the j(0)/j(L) ratios were established. For j(0)/j(L) > 100, the system is under the ohmic control. In the range 1  LT  j(0)/j(L)  LT = 100, there is mixed ohmic-diffusion control. Pure diffusion control appears in the range 0.1  LT  j(0)/j(L)  LT = 1. For j(0)/j(L)  LT = 0.1, the system is activation controlled at low overpotentials. The proposed diagnostic criteria were verified by comparison of the simulated curves with experimentally recorded ones and by morphological analysis of deposits obtained under the different types of control of the metal electrodeposition process.

AB  - The aims of this study were to evaluate the radiopacity, compressive strength, setting time, and porosity of white Portland cement (PC) with the addition of bismuth oxide (Bi2O3), zirconium dioxide (ZrO2), and ytterbium trifluoride (YbF3) after immersion at 37 A degrees C for 7 days in distilled water or phosphate buffer saline. Specimens measuring 8 mm in diameter and 1 mm in thickness were fabricated from PC with the addition of 10, 20, and 30 wt% Bi2O3, ZrO2 or YbF3. ProRoot MTA (Dentsply, Tulsa, OK, USA) and pure PC were used as controls. For radiopacity assessments, specimens were radiographed alongside a tooth slices and an aluminum stepwedge on Extraspeed occlusal dental films (Insight Kodak, Rochester, New York). Mean optical density of each specimen was calculated and used to express radiopacity of the material as an equivalent thickness of aluminum. Compressive strength was measured by using 4-mm diameter and 6-mm high specimens and Universal testing machine. High-pressure mercury intrusion porosimeter (Carlo Erba Porosimeter 2000) was employed to measure the porosity of the specimens. The setting time was measured by using a needle of 100 g in weight. The morphology of specimens was evaluated using a scanning electron microscope (TESCAN Mira3 XMU, USA Inc.). Data were analyzed by one-way ANOVA and post hoc Tukey test (P  LT  0.05). The PC with the addition of at least 10 wt% Bi2O3 and 20 wt% ZrO2 or YbF3 demonstrated greater radiopacity value than the recommended 3 mmAl cut-off. ZrO2 and YbF3 increased the compressive strength of PC, but it was not statistically significant (P > 0.05), while Bi2O3 decreased it (P  LT  0.05). All radiopacifiers significantly increased the porosity of the experimental cements (P  LT  0.05). Bi2O3 extended the setting time of PC (P  LT  0.05), whilst ZrO2 and YbF3 did not significantly affect it (P > 0.05). ZrO2 and YbF3 may be used as a suitable alternative to replace Bi2O3 in MTA without influencing its physical properties.

Mean optical density of each specimen was calculated and used to express radiopacity of the material as an equivalent thickness of aluminum. Compressive strength was measured by using 4-mm diameter and 6-mm high specimens and Universal testing machine. High-pressure mercury intrusion porosimeter (Carlo Erba Porosimeter 2000) was employed to measure the porosity of the specimens. The setting time was measured by using a needle of 100 g in weight. The morphology of specimens was evaluated using a scanning electron microscope (TESCAN Mira3 XMU, USA Inc.). Data were analyzed by one-way ANOVA and post hoc Tukey test (P  LT  0.05). The PC with the addition of at least 10 wt% Bi2O3 and 20 wt% ZrO2 or YbF3 demonstrated greater radiopacity value than the recommended 3 mmAl cut-off. ZrO2 and YbF3 increased the compressive strength of PC, but it was not statistically significant (P > 0.05), while Bi2O3 decreased it (P  LT  0.05). All radiopacifiers significantly increased the porosity of the experimental cements (P  LT  0.05). Bi2O3 extended the setting time of PC (P  LT  0.05), whilst ZrO2 and YbF3 did not significantly affect it (P > 0.05). ZrO2 and YbF3 may be used as a suitable alternative to replace Bi2O3 in MTA without influencing its physical properties.",

AB  - The polarization and morphological characteristics of powder forms of the group of the intermediate metals were examined by the analysis of silver and copper electrodeposition processes at high overpotentials. The pine-like dendrites constructed from the corncob-like forms, which are very similar to each other, were obtained by electrodeposition of these metals at the overpotential belonging to the plateaus of the limiting diffusion current density. A completely different situation was observed by the electrodeposition of silver and copper at the overpotential outside the plateaus of the limiting diffusion current density in the zone with the fast increase in current density with the overpotential. Silver dendrites, which were very similar to silver and copper dendrites obtained inside the plateaus of the limiting diffusion current density, were obtained at the overpotential outside the plateau. Due to the lower overpotential for hydrogen evolution for copper, hydrogen produced during the copper electrodeposition process strongly affected the surface morphology of copper. The same shape polarization curves with completely different surface morphologies of Cu and Ag electrodeposited at overpotentials after the inflection point clearly indicate the importance of morphological analysis in the investigation of polarization characteristics of the electrodeposition systems. The role of hydrogen as a crucial parameter in the continuous change of copper surface morphology from dendrites to honeycomb-like structures was investigated in detail. On the basis of this analysis, the transitional character of the intermediate metals between the normal and inert metals was considered. The typical powder forms characterising electrodeposition of the intermediate metals were also defined and systematized.

AB  - CeO2 coatings were formed on the aluminum after Al surface preparation, by dripping the ceria sol, pre­viously prepared by forced hydrolysis of Ce(NO3)4. The anticorrosive properties of ceria coatings were investigated by the electrochemical impedance spectroscopy (EIS) during the exposure to 0.03% NaCl. The morphology of the coa­tings was examined by the scanning electron microscopy (SEM). EIS data indicated considerably larger corrosion resistance of CeO2-coated aluminum than for bare Al. The corrosion processes on Al below CeO2 coating are sub­jected to more pronounced diffusion limitations in com­parison to the processes below passive aluminum oxide film, as the consequence of the formation of highly com­pact protective coating. The results show that the deposi­tion of ceria coatings is an effective way to improve corro­sion resistance for aluminum.

AB  - In this work, a columnar structure of nickel thin film has been obtained using an advanced deposition technique known as Glancing Angle Deposition. Nickel thin film was deposited on glass sample at the constant emission current of 100 mA. Glass sample was positioned 15 degrees with respect to the nickel vapor flux. The obtained nickel thin film was characterized by Force Modulation Atomic Force Microscopy and by Scanning Electron Microscopy. Analysis indicated that the formation of the columnar structure occurred at the film thickness of 1 μm, which was achieved for the deposition time of 3 hours.

AB  - The processes of lead electrodeposition from the basic (nitrate) and complex (acetate) electrolytes were mutually compared by the analysis of their polarization characteristics and by the scanning electron microscopic (SEM) analysis of the morphology of formed deposits. Although the polarization characteristics of lead recorded from these two electrolytes were relatively similar to each other, the shape of formed dendrites strongly depended on the type of electrolyte. The dendrites composed of stalk and weak developed primary branches (the primary (P) type) were predominantly formed from the basic electrolyte. On the other hand, the very branchy dendrites composed of stalk and of both primary and secondary branches (the secondary (S) type) were mainly electrodeposited from the complex electrolyte. Considering the fact that the application of lead powder in many technologies is closely related with its surface morphology, the special attention was given to the analysis of the type of electrolytes on formation of the different dendritic forms. It was shown that formation of more branchy dendrites from the acetate electrolyte can be ascribed to the lower exchange current density (or to the lower rate of electrochemical process) for this electrolyte than for the nitrate one due to the process of complex formation.

AB  - Electrochemical deposition of polyaniline (PANI) on graphite electrode was performed galvanostaticaly at constant current density in the range of 1.0 - 5.0 mA cm(-2) from aqueous acidic electrolyte containing aniline monomer. Based on ratio of doping/dedoping charge capacities, it was estimated that current density of 2.0 mA cm(-2) was optimal. The structure of the electrochemically synthesized PANI was fibrous, uniform and three dimensional with highly developed surface. Immobilization of glucose oxidise (GOx) was achieved by cross linking via glutaraldehyde and the efficiency of the immobilization was determined spectrophotometrically. Chronoamperometric curves were recorded at different glucose concentrations and used to estimate the apparent Michaelis constant, which was shown to be 0.27 mM. The storage stability of the PANI enzyme electrode was also estimated.

AB  - The effects of plating baths of different composition on the micro- structure and corrosion stability of Zn-Co alloy coatings were studied. Zn-Co alloys with the same Co content were deposited from chloride plating baths containing different amounts of Co2+, as well as from a sulphate-chloride plating bath. The surface morphology and crystallite size were investigated by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The corrosion stability of the Zn-Co alloys was determined by following the change of the open circuit potential with time of immersion in a 3 % NaCl solution and by polarization measurements. The results showed a significant influence of the plating bath on the morphology and corrosion stability of the Zn-Co alloys. The surface of the alloy coatings deposited from the chloride baths were uniform and homogenous, whereas the deposit obtained from the sulphate-chloride bath was quite inhomogeneous. The corrosion stability of the homogenous Zn-Co deposits obtained by deposition from both chloride baths was higher than that of the deposit obtained from the sulphate-chloride bath. An increase in the Co content in the chloride-plating bath resulted in a reduction of the alloy crystallite size and it was shown that the alloy with the smaller crystallites of the two alloy deposits, although having the same chemical content, exhibited a lower corrosion rate.
AB  - U ovom radu je proučavan uticaj vrste rastvora za taloženje na mikrostrukturu i korozionu stabilnost prevlaka Zn-Co legura. Zn-Co legure sa istim sadržajem Co su elektrohemijski taložene iz hloridnih rastvora sa različitim sadržajem jona kobalta, kao i iz sulfatno-hloridnog rastvora. Morfologija površine prevlaka je ispitivana skenirajućom elektronskom mikroskopijom i mikroskopijom atomskih sila. Koroziona stabilnost prevlaka Zn-Co legura je određivana praćenjem promene potencijala otvorenog kola sa vremenom delovanja rastvora NaCl koncentracije 3%, kao i polarizacionim merenjima. Dobijeni rezultati su pokazali značajan uticaj vrste rastvora za taloženje na morfologiju i korozionu stabilnost prevlaka Zn-Co legura. Prevlake Zn-Co legura dobijene iz hloridnih rastvora su homogene, dok su prevlake dobijene iz sulfatno-hloridnog rastvora nehomogene. Koroziona stabilnost prevlaka legura dobijenih iz oba hloridna rastvora je veća u odnosu na stabilnost legura dobijenih iz sulfatno-hloridnog rastvora. Povećanjem sadržaja kobalta u hloridnom rastvoru za taloženje dobijaju se prevlake manjih kristalita i u radu je pokazano kako veličina kristalita utiče na korozionu stabilnost legura sa istim sadržajem kobalta.

The results showed a significant influence of the plating bath on the morphology and corrosion stability of the Zn-Co alloys. The surface of the alloy coatings deposited from the chloride baths were uniform and homogenous, whereas the deposit obtained from the sulphate-chloride bath was quite inhomogeneous. The corrosion stability of the homogenous Zn-Co deposits obtained by deposition from both chloride baths was higher than that of the deposit obtained from the sulphate-chloride bath. An increase in the Co content in the chloride-plating bath resulted in a reduction of the alloy crystallite size and it was shown that the alloy with the smaller crystallites of the two alloy deposits, although having the same chemical content, exhibited a lower corrosion rate., U ovom radu je proučavan uticaj vrste rastvora za taloženje na mikrostrukturu i korozionu stabilnost prevlaka Zn-Co legura. Zn-Co legure sa istim sadržajem Co su elektrohemijski taložene iz hloridnih rastvora sa različitim sadržajem jona kobalta, kao i iz sulfatno-hloridnog rastvora. Morfologija površine prevlaka je ispitivana skenirajućom elektronskom mikroskopijom i mikroskopijom atomskih sila. Koroziona stabilnost prevlaka Zn-Co legura je određivana praćenjem promene potencijala otvorenog kola sa vremenom delovanja rastvora NaCl koncentracije 3%, kao i polarizacionim merenjima. Dobijeni rezultati su pokazali značajan uticaj vrste rastvora za taloženje na morfologiju i korozionu stabilnost prevlaka Zn-Co legura. Prevlake Zn-Co legura dobijene iz hloridnih rastvora su homogene, dok su prevlake dobijene iz sulfatno-hloridnog rastvora nehomogene. Koroziona stabilnost prevlaka legura dobijenih iz oba hloridna rastvora je veća u odnosu na stabilnost legura dobijenih iz sulfatno-hloridnog rastvora. Povećanjem sadržaja kobalta u hloridnom rastvoru za taloženje dobijaju se prevlake manjih kristalita i u radu je pokazano kako veličina kristalita utiče na korozionu stabilnost legura sa istim sadržajem kobalta.",

AB  - The aim of this work was to obtain nanotubular TiO2 layer by anodization of titanium substrate, and to prepare hydroxyapatite (HAP) coatings by electrophoretic deposition over nanotubular TiO2 layer. The presence of fluoride ion in the electrolyte for anodization causes the formation of TiO2 nanotubes. The Ti surface modified with TiO2 nanotubes was used for fabrication of HAP coatings by electrophoretic deposition. Acidic medium provides formation of short nanotubes which are more suitable for deposition of HAP coatings. Ti plates were thermally treated after anodization in order to gain more defined structure of nanotubular TiO2 layer. Compact HAP coatings with good adhesion were produced by electrophoretic deposition on thermally treated and untreated anodized specimens. The results showed that coating mass increases with deposition time, but prolongation of the deposition time causes the decrease of HAP coating adhesion. .

Pokazano je da anodizacija titana u elektrolitu koji sadrži fluoridne jone omogućava formiranje nanotuba TiO2 na površini titana. Površina titana modifikovana nanotubama TiO2 je korišćena kao podloga za kataforetsko taloženje prevlaka hidroksiapatita iz etanolske suspenzije. Kisela sredina za anodizaciju titana omogućava dobijanje kraćih nanotuba koje su se pokazale kao bolja podloga za nanošenje HAP prevlaka.

Kataforetskim taloženjem dobijene su dobro prianjajuće i kompaktne HAP prevlake na termički tretiranim i netretiranim anodiziranim uzorcima. Rezultati pokazuju da pri vremenima taloženja dužim od 45 min dolazi do smanjenja adhezije prevlake hidroksiapatita.

AB  - Electrochemically deposited Zn-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy (AAS) for determination of chemical composition, anodic linear sweep voltammetry (ALSV) and X-ray diffraction (XRD) for phase structure determination, SEM and AFM for surface morphology analysis, and polarization measurements for determination of corrosion properties. The influence of deposition current density and composition of deposition solution on the phase structure, morphology and corrosion properties of Zn-Co alloys were studied. The plating baths used were with low metal concentration, free of additives and deposition was carried out at room temperature, since the aim of the work was to investigate only the influence of different deposition current densities using economically favorable deposition parameters. It was shown that the ratio of cobalt to zinc ions in the plating bath strongly affects the chemical content and phase structure, as well as the morphology and corrosion stability, of Zn-Co alloys. The single-phased Zn-Co alloys showed the best corrosion stability. The alloys deposited at the highest current density from plating bath with the lower ratio of cobalt to zinc ions, as well as the one deposited at the intermediate current density from bath with higher ratio of cobalt to zinc ions, exhibited the lowest corrosion rates. It was also shown that the deposit having smaller crystallite grains (obtained at higher current density), among two alloy deposits having the same chemical content and phase structure, yielded lower corrosion rate.

AB  - Submicron carbon spherical particles were obtained by polycondensation of resorcinol and formaldehyde in a solution and subsequent ultrasonic spray pyrolysis of the prepared sol. Microscopic characterization indicates the regular spherical shape of the obtained particles and sphere diameters in 200-700 nm range. The carbon spheres are amorphous as confirmed by electron diffraction, EELS, XRD and HREM characterization. Activation procedure was performed with H2O in a nitrogen flow for 15 and 30 min at 800 degrees C. The activation procedure preserved the initial spherical shapes of the particles while the particle porosity and specific surface area were increased. The amount of surface oxygen functionalities was also increased by activation procedure as indicated by FTIR analysis.
