[1] Corrosion-electrochemical behavior of chromium deposits obtained from sulfuric acid solutions containing oxalates / V. A. Safonov, L. N. Vykhodtseva, A. A. Edigaryan et al. // Russian Journal of Electrochemistry. — 2001. — Vol. 37, no. 2. — P. 127–134. The corrosion-electrochemical behavior of chromium electrodeposits, which are formed in sulfuric acid solutions of Cr(III) containing oxalates, is studied by taking steady-state polarization measurements in a 0.5 M H2SO4 solution. No region of the metal's active dissolution is observed for such coatings, and the open-circuit potential is localized in the passivity region, i.e. it is substantially displaced in the positive direction as compared with that for metallurgic chromium or the coatings deposited from standard chromium-plating electrolytes. According to XPS data, the surface layer of the passive metal a few nanometers thick includes oxide compounds of chromium and also carbides formed during the coating electrodeposition. Specific features of the corrosion-electrochemical behavior of the deposits are attributed to the presence of carbide compounds of chromium in them, with the compounds playing the role of a cathodic alloying agent.
