　　综述了激光熔凝表面强化技术机理及工艺参数影响的研究现状，结合实际分析目前该技术存在的技术瓶颈，并探究了其数值模拟方面的研究进展。认为研制高效的激光表面处理涂层和采用数值模拟的方式进行激光表面处理技术的机理研究是该领域的主要发展方向。另外，笔者认为可采用多种表面硬化处理方式共同作用，使材料在多种因素交互作用下发挥最大的硬化潜能，如在激光熔凝表面处理后加渗氮等表面化学处理方法。

The strengthening mechanism of Laser Surface Melting (LSM) and the effects of parameters are reviewed. Combined with practice,the technical bottleneck and the numerical simulation of LSM are also anlyzed. The development of efficient coatings used for absorbing laser,and the application of numerical simulation method in studying the mechanism of LSM,are considered to be the main directions in the field. In addition,a variety of surface hardening treatment methods can be adopted to maximize the potential of material hardening,including surface chemical treatment,such as surface nitriding treatment,can be used after LSM.
