Abstract
An unlubricated sliding member composed of a pair of sliding bodies. The sliding part of one sliding body is composed of a ceramic base portion and a thin film of, for example, Nb, which is integrally provided on the surface of the base portion. The sliding part of the other sliding body is composed of a diamond containing surface. The sliding member enables the coefficient of the friction caused when the pair of sliding bodies slide to be reduced, thereby keeping a long life of the sliding member. If the ceramic base portion is further subjected to ion implantation, the wear resistance of the sliding member is enhanced.
