摘　　要：利用0～2kw连续可调CO_2气体激光器对W_18Cr_4V表面进行不同预徐敷材料的激光表面合金化(LSA).考察了合金粉末成分、激光处理工艺参数、预徐敷层厚度对LSA后表面形貌以及耐磨性的影响规律.The surface of Wl8Cr4V Steel precoated with different materials were alloyed by 0-2KW CW CO2 laser. The influences of material composition, processing parameters and precoating thickness on the surface morphology and the wear-resistance were also studied.
