激光表面合金化是利用少量价值昂贵合金粉末熔敷在便宜的材料表面,产生一种表面性能优良的合金层。本文研究45钢(经调质处理)表面铬钼激光合金化及材料性能,获得一些有意义的结果。 实验中使用功率为5kW的CO_2激光器,实用功率2.5kW,光斑直径2mm。由实验得出,合金化层深度与激光束在试样表面扫描 Laser surface alloying is the use of a small amount of expensive alloy powder deposited on the surface of cheap materials, resulting in an excellent surface properties of the alloy layer. In this paper, we studied the chrome-molybdenum laser alloying and material properties of 45 steel (quenched and tempered) surface, and obtained some meaningful results. Experimental use of CO 2 laser power of 5kW, practical power 2.5kW, spot diameter 2mm. The experiment shows that the depth of the alloying layer and the laser beam scan the surface of the sample
