PROCESS FOR STRIPPING NICKEL OR NICKEL-IRON ALLOY PLATING IN A CHROMIC ACID SOLUTION.

摘要

A process for stripping a deposit comprising nickel or a nickel-iron alloy from a substrate metal which comprises immersing the substrate metal with deposit thereon into a stripping bath comprising an aqueous stripping solution comprising chromic acid, utilizing said substrate metal as either or both the anode and cathode of an electrolytic stripping cell and applying an alternating current across the electrodes for a time sufficient to strip the deposit from the substrate metal is disclosed.
