摘　　要：介绍了几种钛合金表面改性的方法,其中激光熔覆技术是一种有发展前景的表面改性方法,可被应用于众多领域。针对陶瓷材料优良耐磨、耐蚀等特性,可被应用于在钛合金表面制备激光熔覆涂层。本文还介绍了Al2O3-Ti O2、Al2O3-Cr2O3和Al2O3-Ti C陶瓷涂层的材料体系及其研究现状,并对于钛合金表面熔覆陶瓷涂层存在的一些问题提出了解决方法。Several titanium alloy surface modification methods were introduced in detail including laser cladding technology, which is a promising method for surface modification with a wide range of applications. Due to its excellent wear resistance, the corrosion resistance and other characteristics of ceramic materials, the materials can be used in the preparation of laser cladding coating on the surface of titanium. Al2O3-TiO2, Al2O3-Cr2O3 and Al2O3-TiC ceramic coating system were introduced. Then, some instructional methods and solutions for some problems of the cladding ceramic coating on the titanium alloy surface were put forward.
