Abstract

A palladium plating bath includes a palladium salt, a complexing agent, and a buffer salt to bring the pH into the range 4 to 5.5 e.g. ammonium chloride or an acid phosphate. The complexing agent is preferably disodium E.D.T.A. Specified concentrations are of palladium salt .01 to .121 mols per litre, complexing agent 2 mols per mol. of palladium salt, of buffer agent .04 mols per litre up to saturation. Base metals include Cu, Ni or Ag and alloys thereof e.g. beryllium copper. Palladium salts specified are chloride, sulphate, acetate, and nitrate. The palladium plated base is adapted for subsequent plating with Ni/Fe alloy as magnetic layer.
