PURPOSE:To reduce remarkably the adhesion wear of a wear resistant member made of a wear resistant material contg. hard particles dispersed in the metallic matrix by projecting part of the hard particles from the surface of the matrix. CONSTITUTION:A wear resistant member is made of a wear resistant material contg. hard particles of 1-100mum particle size dispersed in the metallic matrix. At this time, the surface of the member has hard particles projected from the surface of the matrix by 0.2-5mum. The hard particles are projected from the surface of the matrix by lapping the surface of the member with abrasive grains which are harder than the matrix metal and softer than the hard particles or by chemically leaching out the matrix metal.
