摘　　要：本文叙述了用一台输出功率为２ｋＷ的连续ＣＯ＿２激光器，在２０钢表面上实现了激光熔覆ＷＣ－ＳｉＣ－Ｃｏ的实验方法，并对激光熔覆处理后的样品，从相的组成，显微组织，硬度分布及耐磨性能等方面作了分析，实验结果表明：样品表面的化学成份，显微组织发生了根本性转变，使表面硬度和耐磨性能都得了大幅度提高。In this paper, the experimental procedures are presented for laser cladding WC─SiC─Co hardalloy of the carbon steel surface using a CO_2 laser with an output power of 2kW,We also give a comprehensiveanalysis about the phase structure, the phase morphology,the distribution profile of the hardness and theresistance to abrassior of the sample after treatment. The experimental results indicate that the mechanicalproperties and the chemical composition in the surface layer of material will basically change.
