Abstract

Studied the anodic dissolution of chromium in electrochemical processing nikelhromium alloy ZjS6U. Revealed that the nature of the electrolyte influences the extent to which the oxidation is dissolved chromium: chromium in nitrate electrolytes ionizes only hexavalent form, electrolytes based on sodium chloride is dissolved in chromium hexavalent and the trivalent form. Found that in electrolytes sodium nitrate based primarily hexavalent chromium in solution, the anodic treatment in 15%NaCl chromium (III) is accumulated in the sludge. As the number of the missing electricity in all the electrolytes increases the concentration of chromium ions.
