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 by brazing.
CONSTITUTION: A hard phase made of a carbide such as WC is combined with 20W60vol%, preferably 30W50vol% binder phase made of a metal such as Co, and they are molded and sintered to form a chip 1 made of a sintered hard alloy. The chip 1 is regulated so that the residual pores of ≤50μm size are uniformly distributed at ≤5% porosity. The chip 1 is brazed to the body 2 of a sliding member with a platelike brazing filler metal at the part acting as the sliding surface to be faced to cam 3. Thus, a sliding member with improved wear resistance is obtd.
