Abstract

The invention pertains to the field of chemistry and metallurgy and specifically relates to a method for the electrolytic or electrophoretic production of electrochemical coatings (with a bath based on solutions of decorative trivalent chromium) on a metal or plastic substrate, with trivalent chromium ions, sulfate ions, graphite anodes, hexavalent chromium control and with purification of a dummy cathode in a continuous industrial operation.
