摘　　要：This paper presents the results of a study concerned with the surface hardening of Fe-based alloys and WC-8Co cemented carbide by integrating laser cladding and the electrospark deposition processes.Specimens of low carbon steel were processed firstly by laser cladding with Fe-based alloy powders and then by electrospark deposition with WC-8Co cemented carbide.It is shown that,for these two treatments,the electrospark coating possesses finer microstructure than the laser coating,and the thickness and surface hardness of the electrospark coating can be substantially increased. 关键词：铁基合金粉末电火花沉积激光熔覆硬质合金表面硬化卫生间 YAG 花后
