Abstract:
     The method used in this invention is : put the metal material on the cathode plate in the vacuum reaction chamber. There is also a metal cpd. evaporator inside or outside the vacuum reaction chamber, which is heated by a low voltage electric power source. The metal cpd. is vaporized by heating under vacuum. The vaponized metal cpd. is ionized and proceeds to glow discharge under the action of high voltage D.C. electric field added between the cathode and the anode. The cations bombard the metal material on the cathode plate under glow dischargeing, resulting in the formation of an alloy layer on its surface.
