PURPOSE:To obtain a sliding member having excellent resistance to wear and scuffing with easy surface working in the stage of grinding or polishing the surface of a porous ceramic layer formed on the surface of the sliding part of a member by packing and coating preliminarily the rugged part on the surface of the ceramic layer with a metal. CONSTITUTION:An underlying coat 2 consisting of, for example, an Ni-Al alloy, etc. is formed on the sliding member 1 in order to improve the tight contact characteristic and adhesiveness between the member 1 and the ceramic layer and the ceramic layer 3 is formed thereon. The surface in the rough state of the layer 3 is coated with the metallic layer 4 in such a manner that the rugged part thereof is packed by the metal. The surface of the layer 3 is preferably rough in order to provide the good adhesiveness and adaptability between the layers 3 and 4. The material of the layer 4 is preferably a material such as Ni-Cr alloy having the excellent resistance to wear and scuffing. The sliding part surface of such member 1 is then ground or polished to expose both layers 3 and 4. |
