Abstract

Bismuth oxide layers on a titanium are formed by a plasma electrolytic oxidation (PEO) method from electrolytes containing complex ions EDTA-Bi3+. Electrochemical characteristics – exchange currents, transport coefficients α and β, a and b coefficients in Tafel’s equation are defined. For the obtained systems occurrence of an analytical signal at complexometric titration of salts of Fe (III) is established. The structural features of surface electrodes have been investigated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) techniques. Correlation between morphology, structure of a surface and electrochemical properties of samples is found
