Abstract

A bath for the electrolytic deposition of a palladium-nickel alloy for decorative and/or technical finishes having outstandingly fine and uniform grain structure and satisfactory mixed crystal formation, which enhances brightness, ductility and resistance to the widest variety of corrosive media, and which may improve smoothness, consists of an aqueous solution of palladium- and nickel-amines having a palladium content in the range 5 to 30 g/l and a nickel content in the same range 5 to 30 g/l, together with an addition of sulphonic acid salts, the ration of palladium to nickel being adjusted to that the electrolytically deposited alloy has a palladium content of 30 to 90% by weight, to which is added one or more of the following substances: sodium vinylsulphonate, sodium allylsulphonate, sodium propinesulphonate, sodium methylalylsulphonate, N-pyridinium propylsulpho-betaine, N-pyridinum ethylsulphobetaine, sodium N- benzylpyridinium-2-ethylsulphonate.
