| 摘 要： | 为了研究工艺参数对激光熔覆层微观形貌的影响,以CO2连续激光器为热源,在镍基高温合金基体表面熔覆自配粉末,对不同工艺参数下熔覆层的微观形貌进行了分析.结果表明:在一定范围内,其它工艺参数不变,增加功率,增大扫描速度,晶粒更趋致密细小;工艺参数影响冶金结合带的优劣、胞状晶区的厚薄以及夹杂物的有无和分布.

| Abstract: | Regard the Ni-based high-temperature alloy as substrate and the mixed powder by oneself as layer eladding, the mierostrueture of laser eladding layers under different eraft parameters was studied by CW CO2 laser. The results show that a eertain extent, the other parameters eonstant, inereasing power, inereasing seanning speed, small grains beeome more dense ; The good and bad of metallurgieal belt, the eellular erystal thiekness and the availability and distribution of inelusions are affeeted by the parameters. |
