Beschreibung
Zusammenfassung:	A method for plating by palladium-nickel alloy on imperfect metals and alloys thereof by impulse electrolysis in aqueous solution, containing palladium chloride, nickel (II) chloride hexahydrate, ammonium hydroxide, ammonium chloride, and potassium pyrophosphate. The process of plating is carried out at current density of 8-20 A/dm2, pulse duration of 2.10-3 - 1.10-1 s, and pause duration of 1.10-2-2.10-1 s.
