Abstract

A method for depositing electrolytically a bright decorative chromium on a base metal cathode comprising maintaining a chrome bath containing chromic acid and sulfate in a proportion of 125-550: 1, maintaining an anode in said chromating bath, immersing in said bath a base metal cathode, to apply to said base metal cathode, before immersion, a negative potential value below that sufficient to allow the electrolytic deposition of chromium substantially in all areas of said cathode and to increase the current in said cathode submerged to produce the chromium deposition cathodic current density, thereby depositing chromium on said cathode.
