PALLADIUM BATHS FOR THE ELECTROLESS DEPOSITION

摘要

A palladium alloy plate electrolytically deposited on a catalycally active substrate contains 1-3% of amorphous boron, 1-3% of crystalline palladium or intermetallic cpds. of palladium and hydrogen with the balance amorphous palladium. The alloy plate can be strongly bonded to an electrolytic nickel plate to give a laminate. The palladium alloy deposits have high strength and hardness and are suitable for printed circuit boards, electron switch contacts, or decorative purposes.
