PURPOSE:To obtain the superior abrasion resistance by the solid lubricating material by forming the recessed parts by removing carbides on the surface of a Fe group base and charging the inside of the recessed parts with the solid lubricating material. CONSTITUTION:A material 1 is prepared from the molten material which is carburized to a certain carbon concentration by the carburization of a stainless steel containing a corresponding Cr concentration. The surface of the material 1 is electrolytic-etching-processed by the aqeous solution of oxalic acid, and only the carbide 2 is solved in preference and removed, and a recessed part 3 in porous state is formed. The recessed part 3 of the material is charged with the solid lubricating material 4, and a sliding material is formed. Therefore, the superior load resistance can be obtained because of the solid lubricating material 4 in the recessed part.
