激光表面处理技术是在上世纪70年代大功率激光器出现后,迅速发展起来的一项光、机、电一体化高新技术。这种工艺具有淬硬效果好、自动化程度高、操作简单、能耗低、效率高、工件变形极小和基本无废品等一系列优点。利用激光对零件表面进行处理,可改变零件表面的物理结构、化学成分和金相组织,从而改变零件表面的抗磨损性、耐腐 Laser surface treatment technology in the 1970s after the emergence of high-power laser, the rapid development of a light, mechanical and electrical integration of high-tech. This kind of technology has a series of advantages such as good harden effect, high degree of automation, simple operation, low energy consumption, high efficiency, minimal deformation of the workpiece and no scrap basically. The use of laser on the part surface can change the physical structure of the part surface, chemical composition and microstructure, thereby changing the part surface wear resistance, corrosion
