钛合金具有很高的比强度、优良的耐腐蚀性和高温性能,是航空航天部门广泛使用的高性能材料。但钛合金的摩擦系数大、耐磨性差,因而极大地限制了它在工程上的应用范围。金属表面激光熔覆技术是近年来发展起来的一种新型表面处理工艺。利用高能激光束对材料表面的瞬间加热和熔池 Titanium alloy with high specific strength, excellent corrosion resistance and high temperature performance, is widely used in the aerospace sector, high-performance materials. However, the coefficient of friction of titanium alloy, wear resistance is poor, thus greatly limiting its scope of application of the project. Metal surface laser cladding technology developed in recent years, a new type of surface treatment process. The use of high-energy laser beam on the surface of the material instant heating and pool
