激光表面合金化技术的发展

The Development of Laser Surface Alloying Technique

本文综述了近年来国内外激光表面合金化技术的进展。着重介绍了激光粉末涂敷合金化、激光硬质粒子喷射合金化和激光气体合金化的研究工作及应用实例,并对激光表面合金化技术的发展前景作了展望,提出了当前应主要解决的一些技术问题。

The recent development of laser surface alloying(LSA)tech- nique at home and abroad is reviewed in this paper.The emphases are put on the theoretical research and applications of various LSA technology,such as laser powder alloying,with hard-particle injection and laser gas alloying. The trends and prospects of LSA technique are given and the main technol- ogical question which should be researched taday on the LSA technique are also pointed out.
