一种新型表面处理技术激光处理用于改善材料的表面性能越来越得到重视，处理后的材料可以代替稀贵金属，降低生产成本，延长１件寿命。激光可用于表面处理：（ｌ）控制组分和微结构。激光表面处理可以进行区域性加热和熔化，进行快速加热淬火，从而产生非凡的均质金相微结... A new surface treatment technology Laser treatment is used to improve the surface properties of materials more and more attention, the treated material can replace the precious metals, reduce production costs and extend the life of a piece. Laser can be used for surface treatment: (1) control of components and microstructure. Laser surface treatment can be regional heating and melting, rapid quenching, resulting in extraordinary homogeneous microstructure ...
