Abstract

PURPOSE:To produce a sliding member having excellent wear resistance by melting hardness imparting powder into the surface of a metallic base material by a high-density energy heat ray and adequately adjusting an assist gas to disperse and form may oil holding recesses. CONSTITUTION:A laser beam L condensed to a spot shape by a lens 6 is irradiated from a nozzle 7 of a laser irradiating device 4 to the hardness imparting powder 2 preliminarily coated on the surface of the metallic base material 1 to melt the powder 2 into the material 1 by which a hard layer 3 is formed. The gaseous pressure of the assist gas G such as Ar or N2 which is introduced from a supply pipe 8 and is ejected from the nozzle 7 is regulated to 1.0-3.0kg/cm<2> in this stage. The central molten metal in the remelting part is thereby extruded in the stage of forming the above-mentioned hard layer 3 and the many oil holding recesses 9 enclosed by the hard layer 3 are dispersed and formed. The parts projecting from a sliding contact surface 10 are thereafter ground to obtain the sliding member.
