Abstract

A method of forming a surface finish of trivalent chromium on metal or plastics substrates by electrodeposition from an aqueous plating solution of trivalent chromium ions in which the trivalent chromium is deposited on a layer of silver or silver alloy whereby the color and/or corrosion resistance of the trivalent chromium is comparable to surface finishes of hexavalent chromium. The invention avoids the health and safety risks associated with the electrodeposition of hexavalent chromium surface finishes.
