AB  - Epoxy coatings were formed by cathodic electrodeposition of an epoxy resin on aluminium and modified aluminium surfaces (phosphatized, chromatized-phosphatized and anodized aluminium) using a constant voltage method (resin concentration 10 wt.%, temperature 27 degrees C, applied voltage 250 V). The corrosion behavior of these coatings was investigated during exposure to 3% NaCl using electrochemical impedance spectroscopy (EIS) and polarization measurements. From the dependence of resistance, capacitance and relative permittivity of the coating, obtained from EIS, on the rate of hydrogen evolution reaction in the electrodeposition bath, obtained from polarization curves, it can be observed that the epoxy coating on aluminium and modified aluminium surfaces is a good barrier against the transport of corrosive agents. The time corresponding to contact between electrolyte and aluminium surface under the coating is greater in the case of surface modification by chromato-phosphatized and anodized aluminium than in the case of phosphatize one.

AB  - The electrochemical and transport properties and thermal stability of epoxy coatings electrodeposited on aluminium and modified aluminium surfaces (anodized, phosphatized and chromatized-phosphatized aluminium) have been investigated during exposure to 3% NaCl solution. From the results obtained from electrochemical impedance spectroscopy (EIS), gravimetric liquid sorption experiment and thermogravimetric analysis (TGA) it can be concluded that electrochemical and transport properties of epoxy coatings on anodized and chromatized-phosphatized aluminium are significantly improved with respect to the same epoxy coatings on aluminium and phosphatized aluminium: higher values of pore resistance and charge-transfer resistance and lower values of coating capacitance and double-layer capacitance, from EIS; smaller values of diffusion coefficient of water through epoxy coating, from sorption measurements and smaller amount of absorbed water inside the coating, from TGA. On the other hand, the somewhat lower thermal stability of these coatings was obtained. (C) 2004 Elsevier Ltd. All rights reserved.

The influence of deposition current density on the chemical composition, phase structure and corrosion stability of Zn-Fe alloys was studied. It was shown that deposition current density strongly affects the corrosion stability of Zn-Fe alloys, while Zn-Fe alloy electrodeposited at 4 A dm(-2) exhibited the lowest corrosion rate.

The influence of deposition current density, temperature and composition of deposition solution on the phase structure and corrosion properties of Zn-Co alloys were studied. It was found that Zn-Co alloy obtained from chloride solution at 5 A dm(-2) showed the best corrosion properties, so this alloy was chosen for further examination. Epoxy coating was electrodeposited on steel and steel modified by Zn-Co alloy using constant voltage method.

AB  - By combining the techniques of electrochemical slow potentiodynamic, AC impedance and atomic force microscopy (AFM), ii: was shown that the differences in the anodic dissolution rates of Al in 0.5 NaCl solutions as measured experimentally in the potential region between the corrosion and pitting potential, are mainly due to differences in surface roughness of the electrodes used. It was shown that mechanical grinding and polishing of the electrode surface with emery paper (400 grit) and alumina polishing powder (diameter 0.25 mu m) can produce surfaces differing by a factor of 6 in the roughness factor Ra. By using AFM estimates of the roughness factors a true electrode capacitance of 4.63 mu C cm(-2) and thickness d(ox) approximate to 2.0 nm for the barrier layer of the surface film was estamited. The outer part of the film is porous, partly as amorphous AI(OH)(3), or crystalline bayerite (Al2O3.3H(2)O).

AB  - Organic protective coatings on steel were formed by cathodic electrodeposition of an epoxy resin modified by an amine and isocyanate using a constant voltage method (resin concentration 10% wt, temperature 26 degrees C, applied voltage 250 V). The corrosion behaviour of these coatings was investigated during exposure to different corrosive agents (H2O, 3% NaCl, 3% Na2SO4, 3% sodium salt of 2-naphthol-3,6 disulphonic acid) using a.c. impedance measurements, gravimetric liquid sorption experiments and differential scanning calorimetry (DSC), with the aim of explaining the mechanism of coating degradation. The time required to saturate the coating with pure water, obtained from the sorption data, coincides with the initial increase in coating capacitance and initial decrease in pore resistance, obtained from a.c. impedance measurements, denoting the entry of electrolyte into the coating. The first step of electrolyte penetration through the coating is related to water uptake, when molecules of pure water diffuse in the micropores of polymer net according to Ficks law and it is independent of type and dimensions of ions in the electrolyte. Similar values of enthalpy of vaporization of different volatile electrolytes and the quantity of water inside the coating, obtained from DSC measurements were in agreement with the proposed mechanism. From the calculated diffusion coefficient for coatings where external layers were mechanically removed, it can be concluded that the micropores of the polymer net are homogeneously distributed throughout the coating.
