ABSTRACT:
Method of manufacturing a metallic composite article, with which the surface area of a base member, which surface area consists of a metallic base material, is bonded to a plating material over the entire surface. The base member is to be plated with a layer which is as far as possible homogeneous and thin and the composition of which is freely selectable. For this purpose, the plating material is placed in a sheet-metal cap which is adapted to the surface area to be plated as well as to the adjacent area of the base member surrounding this surface area and overlaps this adjacent area. Once the plating material and sheet-metal cap have been pressed against the base member the sheet-metal cap is evacuated and welded by electron beam, under vacuum, to the base member, whereupon base member, plating material and sheet-metal cap are hot-isostatically pressed. The sheet-metal cap is then removed, leaving the desired, plated base member.
