PURPOSE:To allow a sliding member to show shearing strength and to improve the wear resistance by joining a chip made of a specified sintered hard alloy to the body of the sliding member with a base material in-between. CONSTITUTION:A hard phase made of a carbide such as WC is combined with 20-60vol%, preferably 30-50vol% binder phase made of a metal such as Co, and they are sintered to form a chip 1 made of a sintered hard alloy. The chip 1 is used by >=5%, preferably >=8% of the volume of a base material 2, and the chip 1 is joined to the part of the body 3 of a sliding member acting as the sliding surface with the material 2 in-between to obtain the body 3 of a sliding member having the chip 1 at the part acting as the sliding surface to be faced to a cam 4. Thus, a sliding member with improved wear resistance is obtd. |
