Abstract

A process for producing a sliding member employs a base material having a covering surface and pores, and a layer material comprising a constitutive component for reacting with a constitutive component of the base material. Initially, the layer material comes into contact with at least part of the covering surface of the base material. Next, the both are heated to the sintering temperature of the base material. Thus, a molten liquid occurs at the boundary between the base material and the layer material. Since the solidus temperature of the molten liquid increases with the reaction proceeding, the molten liquid can solidify early to seal the pores at the covering surface of the base material early. Therefore, the layer material remains on the covering surface of the base material, the remaining layer material comes to constitute a sliding surface.
