Abstract
A process for the electrodeposition of palladium in which palladium is electrodeposited from an aqueous plating bath which contains a bath soluble palladium compound, an electrolyte compound and a nitrite compound in an amount sufficient to provide an excess of free nitrite ions relative to the palladium ions. In a preferred embodiment, the bath also contains a buffering agent to maintain the bath pH at from about 6.5 to 7.5. The electrodeposition is carried out using an insoluble anode, while maintaining the excess of free nitrite ions in the bath relative to the palladium ions. In this manner, the plating efficiency of the bath is maintained at a substantially constant, high level for extended periods of plating at current densities in excess of 10 amps per square decimeter.
