| 摘 要： | 本文讨论了强激光瞬间作用金属表面后金属表层特性的改变。分析和实验得出，通过控制入射激光功率密度和作用时间可以实现相交硬化及快速熔化——凝固处理。指出利用脉冲激光并选择适当的工艺参数可以有效地对金属工件进行表面处理以改进其硬度、耐磨及耐腐蚀等性能。

| Abstract: | This paper deals with the characteristic changes of metal surface after transient acting by strong laser. The phase transformation hardening and fast melting-solidification by controlling power intensity and shocking-time of laser pulse have been analysed.it is pointed out that after surfacetreating under proper conditions of laser pulse parameters, the hardness, wear resistance and corrosion reSistance etc. can be improved. |
