On the behavior of palladium electrodeposits on electrical contacts in comparison to gold layers
Abstract
The chemical behavior of palladium coatings was investigated in the presence of corrosive gases and organic vapors from plastics as well as in temperature changes. Studies of the electroplated contact layers of 3 micrometer thickness show that palladium comes very close to high carat gold with 99.5 percent Au. Although not recommended as a universal substitute for gold, palladium behaves better that low carat gold layers with copper/cadmium additions.
