Production of composite metallic material

Abstract

Abstract PURPOSE:To improve adhesive strength by forming a metallic layer of Si, Mn, etc. having a prescribed thickness on the joint surfaces of metallic base materials by a vapor plating method consisting of a physical process then subjecting said surfaces to diffusion joining. CONSTITUTION:At least one kind of the metals selected from the group consisting of Si, Mn, Ni, Cr, Ti, Cu, Ag and Fe are formed to a thin layer of 0.1- 5mum by the vapor plating method of the physical process on the surfaces of the metallic base materials to be joined. The atoms of the evaporating metal are ionized and deposited on the base plates by a pretreatment such as ion bombardment treatment and ionization plating treatment. The coated surfaces of the metallic base materials are superposed on each other and are subjected to the diffusion joining under the conditions of 600-1,200 deg.C heating temp. and >=0.1kg/cm<2> pressurizing force. The diffusion joining of the metallic base material is uniformly progressed by the above-mentioned method and therefore the adhesive strength of the composite material is improved.
