A 316L-Al₂O₃ coating with an introduction of Si was prepared on the surface of 40Cr steel bar by ultra-high-speed laser cladding. Effects of Si on the microstructure, microhardness, wear resistance and corrosion resistance of the coating were investigated by means of optical microscope, scanning electron microscope, microhardness tester, friction and wear testers, electrochemical workstation among others. The results show that the 316L-Al₂O₃ coating is mainly composed of austenite and Al₂O₃. And an addition of Si refines the grain size and also leads to the generation of FeSi intermetallic compounds in the coating, which increases the coating hardness by 18.97%. It is found that the Si-containing 316L-Al₂O₃ coating exhibits improved wear resistance and corrosion resistance, and its wear volume and self-corrosion current density are 19.1 × 10^-3 mm³ and 6.93 × 10^-8 A/cm², respectively.

在40Cr钢棒表面通过超高速激光熔覆制备Si合金化的316L-Al₂O₃涂层。采用光学显微镜、扫描电子显微镜、显微硬度计、摩擦磨损试验机和电化学工作站等研究了Si对涂层微观组织、显微硬度、耐磨和耐蚀性能的影响。结果表明，316L-Al₂O₃涂层主要由奥氏体和Al₂O₃组成，Si的加入细化了晶粒，同时涂层中生成了FeSi金属间化合物，涂层硬度提升了18.97%；含Si的316L-Al₂O₃涂层耐磨、耐蚀性均得到提高，其体积磨损量和自腐蚀电流密度分别为19.1 × 10^-3 mm³和6.93 × 10^-8 A/cm²。
