ABSTRACT:
A palladium-nickel alloy is plated on electrical components, such as frames, pins, connectors and in general various types of electrical contacts. The palladium-nickel alloys are deposited from a plating bath containing a palladosammine chloride, nickel sulfamate, ammonium sulfamate and ammonium hydroxide, the latter operative to solubilize the metals into the ammonia complex and to maintain the necessary bath pH. The bath can be used for either rack plating at current densities of 10 to 25 amperes per square foot or to barrel plate at a plating current of 1 to 3 amperes per square foot.
