ABSTRACT:
A process and solution for electrolytically stripping metal deposits, particularly nickel and nickel-iron alloy deposits from a copper or copper alloy basis metal such as brass, for example, in which the aqueous stripping solution contains controlled effective amounts of halide salts, an organic carboxy acid, metal salts and mixtures thereof and hydrogen ions to provide a pH of less than about 5. The stripping of the metal deposit from the basis metal is effected by immersing the object in the stripping bath while anodically charged and passing electric current through the bath between the cathode and the object for a period of time sufficient to achieve the desired magnitude of stripping of the metal deposit.
