为了提高铝合金零件的耐磨性，对铝青铜合金表面进行了激光熔覆处理。以提高生产率和可控性为目标，分析了离轴和同轴两种可能的喷吹结构，以及轴向运动速度、质量流量和功率调制等工艺参数对粉末喷吹过程的影响。稀释，集水效率和硬度进行了分析所使用的工艺参数和喷嘴配置。(C)2012爱思唯尔有限公司版权所有。
Laser cladding of aluminum bronze alloy has been studied in order to increase the wear resistance of aluminum parts. Aiming a more productive and controlled process, this study analyzes the blown powder process, with two possibilities of blowing configurations that are off-axis and coaxial nozzle, and process parameters, such as axial motion speed, mass flow and power modulation. Dilution, catchment efficiency and hardness were analyzed for the used process parameters and nozzle configurations. (C) 2012 Elsevier B.V. All rights reserved.
