ABSTRACT:
A method of producing a sliding composite material. The method comprises the step of: forming an adhesive layer bonded to the surface of a metal strip by sintering a powder for the adhesive layer which contains no solid lubricant and which is disposed onto the surface of the metal strip; forming a surface layer by sintering another powder for the surface layer which contains a solid lubricant and which is disposed onto the sintered adhesive layer; and rolling the resulting layers and the metal strip to obtain the composite material.
