Abstract

A method of producing a corrosion protective coating on a metal substrate, which is to pass a current from an anode through an aqueous acidic nickel plating electrolyte solution containing nickel ions and a soluble amine in the bath, up to a cathodic workpiece, for a period of time sufficient to form a nickel deposit and keep in the bath at least about 1 mg/l of a metal cation whose precipitation occurs at a lower pH than that of nickel in said solution and then electrodeposit a layer of chrome on the nickel-plated substrate, thereby producing a microporous chrome coating.
