Abstract
A novel palladium-nickel alloy plating solution provides a uniform electrodeposited film with excellent gloss at a high electric current density. A palladium-nickel alloy plating solution comprises a water-soluble palladium salt, a water-soluble nickel salt, ammonia, an ammonium salt, and 3-pyridinesulfonic acid, which are solved in water. Further additives may be added in the solution.
Claims6
