Abstract:
Method of electrolytically post-treating an electrolytically chromate treated or metallic chromium plated steel sheet comprises anodically treating the said electrolytically chromate threated or metallic chromium plated steel sheet in an electrolyte other than an aqueous solution easily dissolving metallic chromium. The anodically treated steel sheet can be treated cathodically in an electrolyte with the said anodically treated steel sheet being employed as the cathode.
