激光熔覆技术是指以不同的填料方式在被涂覆基体表面上放置选择的涂层材料经激光辐照使之和基体表面一薄层同时熔化,并快速凝固后形成稀释度极低、与基体材料成冶金结合的表面涂层,从而显著改善基体材料表面的耐磨、耐蚀、耐热、抗氧化及电器特性等的工艺方法。它始于1974年,而 Laser cladding technology refers to the different filler material placed on the surface of the coated substrate selected by the laser irradiation so that the substrate surface and a thin layer of molten at the same time, and rapid solidification to form a very low dilution, and The base material is a metallurgical bonded surface coating, which significantly improves the wear resistance, corrosion resistance, heat resistance, oxidation resistance and electrical properties of the substrate surface. It started in 1974, and
