Abstract

Procedure for the electroplating of a chrome plating on a base metal, comprising passing current from an anode to a cathode, at least a portion of which contains a conductive metal layer, through an acidic aqueous solution for chroming, providing the minus a hexavalent chromium ion chromium compound for chromium electroplating, and aluminum ions in combination with fluoride and sulfate ions, maintaining a molar ratio of total fluoride to total aluminum of 0.5 to less than 6, for a time sufficient to deposit a chrome electrolytic coating.
