PURPOSE:To improve the wear resistance of the sliding surface of metallic sliding parts by forming a composite Fe-P or Fe-Ni-P plating layer contg. pulverous wear resistant particles and the short fibers of metallic compd. on said sliding surface. CONSTITUTION:The composite plating layer dispersed with 5-30vol% pulverous wear resistant particles of hard metallic oxide, metallic nitride and metallic carbide such as Al2O3, Si3N4, SiC, ZrO2 and TiO2 having <10mu grain size and 5-30vol% the short fibers 5 of the metallic oxide, metallic carbide and metallic oxide such as Al2O3, Si3N4, SiC and ZnO2 having 0.05-1mu fiber diameter and 10-200mum length into an Fe-P or Fe-Ni-P alloy base 3 consisting of 2-15wt% P, 85-98wt% Fe or 2-15wt% P, 10-40wt% Ni and 50-88wt% Fe is formed on the sliding surface 2 of the metallic sliding parts 1, by which the wear resistance of the sliding surface 2 is improved.
