なるという問題があった。In other words, conventional sliding parts include metal parts such as cast iron whose sliding surfaces are nitrided or hard chromium plated to improve wear resistance, and ceramic parts made of silicon nitride, which have improved wear resistance. Ceramic parts made entirely of superior ceramic materials are known, but metal parts have limited wear resistance, and parts made entirely of ceramic are not only expensive but also have excessive quality. There was a problem with becoming.

して使用することができなかった。Therefore, there is a desire for metal parts in which only the sliding surfaces are made of wear-resistant ceramic members, but it is difficult to integrate ceramic members and metal members, especially silicon nitride ceramic members and steel materials11'c Therefore, it could not be used as a mechanical part.

この場′合は突起部を４１する形状が好ましい。The Viramix member used in the present invention is preferably one with excellent wear resistance, such as non-oxide ceramics such as silicon nitride, silicon carbide, Xialon, and zirconia, which are collectively referred to as fine ceramics. In some cases, it may be desirable to form an oxide film of a compound such as silicon dioxide or alumina on the surface of these materials in order to form a conductive layer. In addition, its shape has a mating part on the joint surface,
