ABSTRACT:
A porous metal supporting a composite portion of an aluminum alloy is formed by means of pressing a pair of surfaces thereof, and then chromium is cemented by diffusion before the molten aluminum alloy is penetrated thereinto. Thus, not only the mechanical strength of the interface between the aluminum alloy and the porous metal, but also the wear resistance of the composite portion can be improved.
