ABSTRACT:
An electrodeposited bright coating simulating in appearance that of chromium is formed on a metal-bearing substrate with substantial production economies by contacting the metallic layer on the susbstrate with an aqueous solution including therein a source of cobalt, nickel or iron ions; a source of tin ions; and a complexing agent selected from the group consisting of gluconate, glucoheptonate, or mixtures thereof. If desired, the aqueous solution may include a source of zinc ions. During the process the thickness of the chromium-like appearance coating is controlled so that it does not substantially exceed five micrometers.
