    摘要： A mechanical part comprises a sliding section and a sleeve section which are prepared separately. The sliding section is made of a wear resisting material such as ceramics and formed with a planar sliding surface at one of the sides thereof. The sliding section is further formed with a joining portion at the outer periphery thereof. The sleeve section is made of metal and formed with a joining portion at the inner periphery thereof. The joining portions of the sliding section and the sleeve section are joined by interference fit or the like, whereby to allow the sliding surface of the sleeve section to be formed into a crowned shape.

    摘要： A tappet for an internal combustion engine consists of a tappet main body and a ceramic seat plate brazed to the tappet main body. The tappet main body is made up of a first part made of low carbon steel and a second part made of metal. In manufacture, the first and second parts are first welded together to constitute the tappet main body, and then the ceramic seat is brazed to the tappet main body. The low carbon steel forming the first part of the tappet main body has such a property that when carburized it can be hardened by making use of the heat for the brazing, and the metal forming the second part of the tappet main body has such a property that it can be hardened by making use of the heat for the brazing.
