摘　　要：本文介绍大功率ＣＯ＿２激光束在４５钢表面涂敷ＷＣ－ＴｉＮ－Ｃｏ，进行了激光熔覆处理，对处理后样品的显微组织、物相、硬度分布和耐磨性能进行了测试和分析，结果表明：４５钢表面的化学成分和显微组织发生了根本性的变化，硬度和耐磨性得到了很大提高。In this paper,the experimental study of laser smelting WC-TiN-Co alloy cladded on the 45 # steel surface by using a high power CO_2 laser is presented. The surface features, such as phase structure , phase morphology , hardness,antiabra-tiveness,are analyzed. The experimental results show that there are the cardinal changes of the chemical composition and the microstructure of treated 45 # steel sur-face,and the hardness and antiabrativeness of the surface are greatly improved.
