| 摘 要： | 以提高耐磨性为主的大面积激光相变硬化必须采用光斑搭接方法，在搭接处的回火带是不可避免的。本文研究了大面积激光相变硬化硬度分布特征，研究搭接量与回火带的关系，找出适合生产实际需要的搭接方案，以解决大面积激光相变硬化技术在汽车，冶金行业中的大型模具，轴等零件等强化中的瓶颈问题。

| Abstract: | The big area laser transformation hardening must adopt the methods of facular joint in giving priority to attrition,and the tempering zone can't be avoided in the joint. This paper studies the hardness distribution character in big area laser transformation hardening and the relationship between joint measure and the tempering zone. It is intended to find out a practical cap joint method in order to solve the bottle\|neck problem in applying big area laser transformation hardening technology in large mould and axis hardening in auto and metallurgy industries. |
