AB  - The influence of steel surface pretreatment with different types of iron-phosphate coatings on the corrosion stability and adhesion characteristics of polyester coatings on steel was investigated. The phosphate coating was chemically deposited either from the simple novel plating bath, or with the addition of NaNO(2), as an accelerator in the plating bath. The morphology of phosphate coatings was investigated using atomic force microscopy (AFM). The corrosion stability of polyester coatings on steel pretreated by iron-phosphate coatings was investigated by electrochemical impedance spectroscopy (EIS) in 3% NaCl solution, while "dry" and "wet" adhesion were measured by a direct pull-off standardized procedure. It was shown that greater values of pore resistance. R(p), and smaller values of coating capacitance of polyester coating, C(c), on steel pretreated with iron-phosphate coating were obtained, as compared to polyester coating on steel phosphated with accelerator, and on the bare steel. The surface roughness of phosphate coating deposited on steel from the bath without accelerator is favorable in forming stronger bonds with polyester coating. Namely, the dry and wet adhesion measurements are in accordance with EIS measurements in 3% NaCl solution, i.e. lower adhesion values were obtained for polyester coating on steel phosphated with accelerator and on the bare steel, while the iron-phosphate pretreatment from the novel bath enhanced the adhesion of polyester coating on steel.

AB  - One of the most important factors in corrosion prevention by protective coatings is the coating adhesion loss under environmental influence. Thus, adhesion strength is often used when characterizing protective properties of organic coatings on a metal substrate. In order to improve the adhesion of organic coating the metal substrate is often pretreated in some way. In this work, the adhesion of polyester coatings on differently pretreated aluminium surface (by anodizing, with and without sealing, by phosphating and by silane film deposition) was examined. The dry and wet adhesion of polyester coatings were measured by a direct pull-off standardized procedure, as well as indirectly by NMP test. It was shown that under dry test conditions all polyester coatings showed very good adhesion, but that aluminium surface pretreated by silane film showed superior adhesion. The overall increase of wet adhesion for polyester coating on aluminium pretreated by silane film was maintained throughout the whole investigated time period. The different trends in the change of adhesion of polyester coatings were observed for different aluminium pretreatments during exposure to the corrosive agent (3% NaCl solution). The highest adhesion reduction was obtained for polyester coating on aluminium pretreated with phosphate coating. The corrosion stability of polyester coated aluminium was investigated by electrochemical impedance spectroscopy in 3% NaCl solution. The results confirmed good protective properties of polyester coating on aluminium pretreated with silane film, i.e. greater values of pore resistance and smaller values of coating capacitance were obtained in respect to other protective systems, whereas charge-transfer resistance and double-layer capacitance were not measurable during 2 months of exposure to a corrosive agent.

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.

The voltammogram of the Ti(0.6)Ir(0.4)O(2)/Ti electrode showed well-resolved peaks related to Ir redox transitions, which are responsible for the enhanced charge storage ability of IrO(2)-containing coatings. Redox transitions of Ir were also registered in the high-frequency domain of the ac impedance spectra of the coatings as a semicircle with characteristics insensitive to the electrolyte composition and to the electrode potential prior to OER. However, the semicircle characteristics were different for the two IrO(2)-containing coatings, as well as at potentials outside the OER in comparison to those at which the OER occurs.

AB  - The changes in capacitive behavior of C/H(x)RuO(y) composite material prepared by impregnating the Vulcan (R) XC 72R carbon black with oxide sols of different particle size are investigated as the electrolyte penetrates through the thin layer of the Nafion (R)-covered composite. The techniques of cyclic voltammetry and electrochemical impedance spectroscopy are used. Results of the investigation reveal the influence of potential cycling and the exposure time to the electrolyte on registered capacitive characteristics of composite. The cycling in a wide potential range causes the decrease in energy storage ability which depends on oxide particle size. Impedance measurements, however, show that the ability initially decreases and subsequently increases during exposure to the electrolyte as the consequence of the presence of Nafion (R) top-layer. Due to wettability and resistance issues, Nafion (R) top-layer can affect the pseudo-capacitive characteristics, and the energy storage ability of the composite consequently decreases.

The cycling in a wide potential range causes the decrease in energy storage ability which depends on oxide particle size. Impedance measurements, however, show that the ability initially decreases and subsequently increases during exposure to the electrolyte as the consequence of the presence of Nafion (R) top-layer. Due to wettability and resistance issues, Nafion (R) top-layer can affect the pseudo-capacitive characteristics, and the energy storage ability of the composite consequently decreases.",

AB  - The influence of hot-dip galvanized steel (HDG) surface pretreatment with phosphate coatings on the corrosion stability and adhesion characteristics of epoxy coatings electrodeposited on HDG steel was investigated. Phosphate coatings were deposited on hot-dip galvanized steel from baths with different concentrations of NaF (0.1, 0.5 and 1.0 g dm-3) and at different temperatures (50, 65 and 80 °C). The influence of fluoride ion concentration in the phosphating bath, as well as the deposition temperature of the bath, on the adhesion characteristics and corrosion stability of epoxy coatings on phosphated HDG steel was investigated. The dry and wet adhesions were measured by a direct pull-off standardized procedure, as well as indirectly by NMP test, while corrosion stability was investigated by electrochemical impedance spectroscopy (EIS). It was shown that under dry testing conditions all the samples exhibited very good adhesion. However, the different trends of adhesion loss of different protective systems during exposure to corrosive agent (3% NaCl solution) were observed. The lowest adhesion values were obtained for epoxy coating on hot-dip galvanized steel, while the phosphate pretreatments significantly increase the adhesion of epoxy coatings. The highest values of adhesion strength were obtained for epoxy coating on HDG steel modified by phosphate coating deposited at 65 °C with 0.5 g dm-3 NaF in the phosphating bath. EIS measurements in 3% NaCl solution are in accordance with adhesion measurements, i.e. greater values of charge-transfer resistance and smaller values of double-layer capacitance were obtained, as compared to other protective systems.

AB  - The photoelectrochemical properties of a sol-gel prepared titanium oxide coating applied onto a Ti substrate were investigated. The oxide coating was formed from an inorganic sol thermally treated in air at 350°C. The coating consisted of agglomerates of narrow size distribution around 100 nm. The photoelectrochemical characteristics were evaluated by investigating the changes in the open circuit potential, current transients and impedance characteristics of a Ti/TiO2 electrode upon illumination by UV light in H2SO4 solution and in the oxidation of benzyl alcohol. The electrode was found to be active for photoelectrochemical reactions in the investigated solutions.

AB  - The adhesion and electrochemical properties of epoxy coatings electrodeposited on hot-dip galvanized steel with and without passive films were investigated during exposure to 3% NaCl. The passive films were formed in hot air, in boiling water and by chromating. Adhesion was measured both by a standardized pull-off method and by swelling in N-methyl pyrrolidone. Pretreatment of hot-dip galvanized steel with passive film formed in hot air increases both dry and wet adhesion strength of the epoxy coating compared to pretreatment with passive film formed in boiling water and chromate coating. The overall increase of wet adhesion for this sample was maintained throughout the whole investigated time period. It was shown that the change in adhesion of epoxy coating on a chromate coating is smallest of all investigated samples, although the initial value of adhesion on this surface had the lowest value. The corrosion stability of coated Zn samples pretreated by different methods, was investigated by electrochemical impedance spectroscopy and in the initial time of exposure to NaCl the highest values of pore resistance were also obtained for the epoxy coating on Zn pretreated in hot air, whereas the epoxy coating on a HDG steel with a chromate coating showed the smallest change in electrochemical properties (pore resistance, coating capacitance, charge-transfer resistance) during prolonged exposure time.

AB  - The capacitive properties of titanium electrodes with an active porous RuO2 coating were investigated in H2SO4 and NaCl solution by cyclic voltammetry and electrochemical impedance spectroscopy. Electrodes with two different masses of coating (thin and thick coating) were prepared from an ink suspension of the oxide synthesized by hydrolysis of ruthenium-ethoxide in ethanolic solution. The capacitive characteristics were found to be dependent on the coating mass and the electrolyte composition. It was shown that the impedance data of the prepared electrodes, registered at the open circuit potential, can be interpreted by a transmission line model of the equivalent electrical circuit. In this interpretation, the number of parallel branches containing resistor and capacitor in series is different for thin and thick coatings and in different electrolytes. More branches were required to describe the impedance behavior of the thick coating and to simulate the impedance data in NaCl solution. Simulation of the impedance data with the transmission line model of the equivalent circuit was also used to analyze the distribution of capacitance throughout the porous coating. The simulation indicated a more pronounced contribution of the capacitance of the outer coating layer to the total coating capacitance in the case of the proton-rich electrolyte. On the other hand, the presence of chloride ions in the electrolyte promoted a charging process at the inner coating surface, which is hardly accessible to the electrolyte.

AB  - Chromium dissolution in aqueous sulfuric acid solution of pH 1 was studied electrochemically on chromium electrodes with different crystallographic structures. A slow potentiodynamic method was used for the electrochemical measurements in deaerated solutions (purged with nitrogen),while the Cr(III) ions in the solution after the corrosion were determined by atomic absorption spectrometry. Three electrode materials with a very dominant crystallite orientation resembling single crystal structures (i.e., 111 and 110) confirmed by the electron backscattering diffraction (EBSD), were used in the experiments. The (111) structures were somewhat more active electrochemically (both anodic and cathodic) than the (110) structure. However, Cr electrochemically deposited in standard plating bath, assumed from literature data to has also the (111) structure, was more than 4 times active for anodic dissolution and, by the same number, less active for cathodic hydrogen evolution. The concentrations of Cr(III) ions determined in the solution after definite times of corrosion of all the materials showed almost two times larger dissolution rates than observed electrochemically by three different electrochemical methods (Wagner-Traud, Stern-Geary, electrochemical impedance spectroscopy). This is explained by the simultaneous occurrence of potential independent chemical dissolution of Cr, by a direct reaction of metallic Cr with H2O molecules, proposed a long time ago by Kolotyrkin and coworkers. .

AB  - The characteristics of a ternary oxide coating, on titanium, which consisted of TiO2, RuO2 and IrO2 in the molar ratio 0.6:0.3:0.1, calculated on the metal atom, were investigated for potential application for cathodic protection in a seawater environment. The oxide coatings on titanium were prepared by the sol-gel procedure from a mixture of inorganic oxide sols, which were obtained by forced hydrolysis of metal chlorides. The morphology of the coating was examined by scanning electron microscopy. The electrochemical properties of activated titanium anodes were investigated by cyclic voltammetry and polarization measurements in a H2SO4- and NaCl-containing electrolyte, as well as in seawater sampled on the Adriatic coast in Tivat, Montenegro. The anode stability during operation in seawater was investigated by the galvanostatic accelerated corrosion stability test. The morphology and electrochemical characteristics of the ternary coating are compared to that of a sol-gel-prepared binary Ti0.6Ru0.4O2 coating. The activity of the ternary coating was similar to that of the binary Ti0.6Ru0.4O2 coating in the investigated solutions. However, the stability in seawater is found to be considerably greater for the ternary coating.

Oksidna prevlaka na titanu formirana je sol-gel postupkom iz smeše neorganskih oksidnih solova, koji su dobijeni forsiranom hidrolizom hlorida metala.

Stabilnost anode tokom rada u morskoj vodi ispitivana je galvanostatski, ubrzanim testom stabilnosti. Dobijene prevlake upoređene su sa dvojnom Ti0,6Ru0,4O2 prevlakom, u pogledu morfologije i elektrohemiskih karakteristika. Pokazano je da su trojna i dvojna prevlaka slične aktivnosti u ispitivanim rastvorima. Međutim, u morskoj vodi stabilnost trojne prevlake je znatno veća.

AB  - The potentiodynamic study of the electrochemical behavior of austenitic 304 stainless steel in deaerated aqueous sulfuric acid of pH 1 revealed that the steel achieved a stable corrosion potential of ca. - 0.350 V (SCE) independent of whether the electrode had previously been cathodically "activated" or anodically passivated. It was also shown that the experimentally observed anodic peak was not the usually obtained anodic passivation peak, as is the case with a number of metal, but an artifact due to the anodic oxidation of hydrogen absorbed during the previously employed cathodic polarization and hydrogen evolution, intended to activate the initially passive surface, or even hydrogen absorbed on the open circuit potential. It was shown that this potential establishes and electrochemical corrosion potential of the Wagner-Traud type due to the evolution of cathodic hydrogen on a passivated steel surface and anodic metal dissolution through the passive layer. It was impossible to activate 304 stainless steel in sulfuric acid of pH 1 by cathodic polarization, and the usually observed anodic peak obtained under these conditions should not be considered as an active metal dissolution process and a passivation anodic peak, but rather as an artifact due to the electrochemical oxidation of the in the steel absorbed hydrogen.
AB  - Potenciodinamička ispitivanja elektrohemijskog ponašanja nerđajućeg čelika 304 u deaeriranoj sumpornoj kiselini sa pH 1 pokazala su da se na čeliku uspostavlja stabilan korozioni potencijal od - 0,350 V(ZKE) nezavisno od toga da li je elektroda prethodno katodno tretirana radi "aktivacije", ili je površina bila pasivirana. Pokazano je, takođe, da eksperimentalno dobijeni anodni maksimum na potenciodinamičkoj krivi pozitivnije od korozionog potencijala nije anodni pasivacioni maksimum koji se obično dobija pri anodnoj polarizaciji većeg broja metala u sličnim uslovima, već eksperimentalni artefakt koji nastaje zbog anodne oksidacije vodonika apsorbovanog unutar čelika tokom katodnog "aktiviranja" ili čak i pri dužem držanju na korozionom potencijalu. Pokazano je da je spontano formirani potencijal otvorenog kola zapravo korozioni potencijal koji nastaje kao mešoviti potencijal Vagner-Traudovog tipa suprotnim delovawem katodne reakcije izdvajanja vodonika na pasivnom sloju i anodnog rastvaranja čelika kroz pasivni sloj. Nije bilo mogućno katodnom "aktivacijom" i dugotrajnijom katodnom polarizacijom do značajno negativnih potencijala i vrlo velikih katodnih struja da se pasivni sloj ukloni i postigne aktivno elektrohemijsko rastvaranje metala bez prisustva pasivnog sloja, tj. slobodna metalna površina. Stoga, često eksperimentalno konstatovan anodni maksimum na ovakvim čelicima ne treba da se interpretira kao anodno rastvaranje sa pasivacionim maksimumom, već kao posledica anodne oksidacije apsorbovanog vodonika u pasivnom čeliku, a koji se pod ovim uslovima ne može elektrohemijski aktivirati, odn. depasivirati.

abstract = "The potentiodynamic study of the electrochemical behavior of austenitic 304 stainless steel in deaerated aqueous sulfuric acid of pH 1 revealed that the steel achieved a stable corrosion potential of ca. - 0.350 V (SCE) independent of whether the electrode had previously been cathodically "activated" or anodically passivated. It was also shown that the experimentally observed anodic peak was not the usually obtained anodic passivation peak, as is the case with a number of metal, but an artifact due to the anodic oxidation of hydrogen absorbed during the previously employed cathodic polarization and hydrogen evolution, intended to activate the initially passive surface, or even hydrogen absorbed on the open circuit potential. It was shown that this potential establishes and electrochemical corrosion potential of the Wagner-Traud type due to the evolution of cathodic hydrogen on a passivated steel surface and anodic metal dissolution through the passive layer. It was impossible to activate 304 stainless steel in sulfuric acid of pH 1 by cathodic polarization, and the usually observed anodic peak obtained under these conditions should not be considered as an active metal dissolution process and a passivation anodic peak, but rather as an artifact due to the electrochemical oxidation of the in the steel absorbed hydrogen., Potenciodinamička ispitivanja elektrohemijskog ponašanja nerđajućeg čelika 304 u deaeriranoj sumpornoj kiselini sa pH 1 pokazala su da se na čeliku uspostavlja stabilan korozioni potencijal od - 0,350 V(ZKE) nezavisno od toga da li je elektroda prethodno katodno tretirana radi "aktivacije", ili je površina bila pasivirana. Pokazano je, takođe, da eksperimentalno dobijeni anodni maksimum na potenciodinamičkoj krivi pozitivnije od korozionog potencijala nije anodni pasivacioni maksimum koji se obično dobija pri anodnoj polarizaciji većeg broja metala u sličnim uslovima, već eksperimentalni artefakt koji nastaje zbog anodne oksidacije vodonika apsorbovanog unutar čelika tokom katodnog "aktiviranja" ili čak i pri dužem držanju na korozionom potencijalu. Pokazano je da je spontano formirani potencijal otvorenog kola zapravo korozioni potencijal koji nastaje kao mešoviti potencijal Vagner-Traudovog tipa suprotnim delovawem katodne reakcije izdvajanja vodonika na pasivnom sloju i anodnog rastvaranja čelika kroz pasivni sloj. Nije bilo mogućno katodnom "aktivacijom" i dugotrajnijom katodnom polarizacijom do značajno negativnih potencijala i vrlo velikih katodnih struja da se pasivni sloj ukloni i postigne aktivno elektrohemijsko rastvaranje metala bez prisustva pasivnog sloja, tj. slobodna metalna površina. Stoga, često eksperimentalno konstatovan anodni maksimum na ovakvim čelicima ne treba da se interpretira kao anodno rastvaranje sa pasivacionim maksimumom, već kao posledica anodne oksidacije apsorbovanog vodonika u pasivnom čeliku, a koji se pod ovim uslovima ne može elektrohemijski aktivirati, odn. depasivirati.",

AB  - Open circuit potential measurements and cyclic voltammetry of chromium in deaerated aqueous H2SO4 solution of pH 1 without and containing NaCl in the concentration range 0.5 - 4 M revealed that chromium exhibits two stable open circuit potentials having the character of a Wagner-Traud corrosion potential. One, E corr.1, was established on the passive surface formed by exposing Cr previously to air or passivated potentiostacially in a controlled manner, and the second one, E corr,2, at the bare Cr surface obtained by prolonged cathodic activation. There is a small difference in the E corr,1 values as a function of the passive layer properties. Addition of NaCl accelerates the hydrogen evolution reaction on the passive surface to some extent, while the same reaction on the bare surface was not affected by NaCl. On the other hand, presence of NaCl accelerates the anodic reaction on the bare surface, and it activates the dissolution of the passive layer so that the passive currents increase with addition of NaCl. This effect is so large that at concentration of NaCl larger than 3 M, the destruction of the passive layer was so fast that in a matter of seconds the Cr was activated, and the only one stable corrosion potential observed was E corr.2. No pitting of Cr in the presence of NaCl was observed up to the transpassive potentials.

Jedan korozioni potencijal, E corr.1 , se uspostavljao na pasiviranoj površini, koja se formira prethodnim izlaganjem Cr vazduhu, ili poteciostatskim pasiviranjem na kontrolisan način, a drugi, E corr.2 , se obrazovao na goloj površini Cr koja je formirana katodnom aktivacijom u dovoljno dugom periodu vremena. Postoji izvesna mala razlika u vrednostima E corr.1 kao funkcija osobina pasivnog sloja. Dodatak NaCl u određenoj meri ubrzava reakciju izdvajanja vodonika na pasiviranoj površini, dok NaCl nema uticaja na istu reakciju na goloj površini Cr. Sa druge strane prisustvo NaCl ubrzava anodnu reakciju na goloj površini hroma i aktivira rastvaranje pasivnog sloja, tako da se struja pasivacije povećava sa dodatkom NaCl. Uticaj NaCl je toliko veliki, da pri koncentracijama većim od 3M, razaranje pasivnog sloja postaje brzo, da se Cr za vreme od nekoliko sekundi aktivira i tada se uočava samo jedan stabilni korozioni potencijal E corr.2 . Nije uočena pojava pitinga u prisustvu NaCl, sve do potencijala u transpasivnoj oblasti.

AB  - Titanium anodes with an active RuO2 coating of two different thicknesses were prepared from the oxide suspended in ethanol ("ink" method), while the oxide itself was synthesized by the hydrolysis of ruthenium ethoxide in an ethanolic solution (alkoxide route). The morphology of prepared oxide was examined by scanning electron microscopy. The electrochemical properties of the prepared Ti/RuO2 anodes, involving their cyclic voltammetric behavior in H2SO4 and NaCl solutions, activity in the chlorine and oxygen evolution reaction, impedance behavior in H2SO4, and stability during electrolysis in dilute chloride solutions, were investigated. The performances of the anodes are compared to those of a Ti/RuO2 anode prepared by the sol-gel procedure from an oxide sol obtained by the forced hydrolysis of ruthenium chloride in acid solution. The anodes prepared via the alkoxide route showed a higher capacitance and activity for the chlorine evolution reaction than the anode prepared by the inorganic sol-gel procedure. The results of the stability test showed that the utilization of the coating active material is better when the anodes were prepared via the alkoxide route than via the inorganic sol-gel procedure, particularly for anodes with a smaller mass of coating. The different rates of loss of activity indicate a degradation mechanism for the anodes prepared via the alkoxide route in which electrochemical dissolution of RuO2 from the coating surface prevails over the growth of an insulating TiO2 layer in the coating/Ti substrate interphase. The effect of RuO2 dissolution from the coating surface increases with increasing coating mass.

Morfologija dobijenog oksida ispitivana je skenirajućom elektronskom mikroskopijom. Ispitivana su elektrohemijska svojstva formiranih anoda, koja podrazumevaju ciklično-voltametrijsko ponašanje u rastvorima H 2SO4 i NaCl, aktivnost u reakcijama izdvajanja hlora i kiseonika, impedansno pona- šanje i stabilnost tokom elektrolize razblaženih rastvora hlorida. Karakteristike dobijenih anoda upoređene su sa karakteristikama anode formirane sol-gel postupkom iz oksidnog sola dobijenog forsiranom hidrolizom rutenijum(III)-hlorida u kiseloj sredini (5 mol dm-3HCl). Anode formirane alkoksidnim postupkom imaju veću kapacitivnost i aktivnost za reakciju izdvajanja hlora od anode dobijene sol-gel postupkom iz neorganskog sola. Rezultati testa stabilnosti u rastvoru hlorida pokazuju da je iskorišćenje aktivnog materijala prevlake takođe bolje kod anoda dobijenih alkoksidnim postupkom, naročito za anodu sa manjom debljinom prevlake. Rezultati ukazuju na to da u mehanizmu gubitka aktivnosti anoda dobijenih alkoksidnim postupkom elektrohemijsko rastvaranje oksida rutenijuma sa površine prevlake preovlađuje u odnosu na rast izolatorskog sloja oksida titana u međufazi prevlaka/ titanska podloga. Efekt rastvaranja RuO2 sa površine je izraženiji kod prevlake veće debljine.
