ABSTRACT:
Electroplating baths suitable for obtaining white deposits of palladium metal. The bath comprises diaminodinitrite, an ammonium salt, and a sufficient amount of ammonium hydroxide to obtain a bath pH of about 9. Buffers such as ammonium biborate may be employed to maintain the necessary bath pH during electroplating operations to produce a thin, white deposit of palladium metal. The process of using such electroplating baths to produce white deposits of palladium metal on substrates is also disclosed and claimed.
