将六轴机器人、送粉装置和专用送粉喷嘴结合起来的Nd：YAG激光机器人熔覆系统用于粉末熔覆工艺。采用Stellite 6+WC混合粉末在低碳钢（SM 400 B）表面进行了熔覆试验。研究了渗层深度、开裂行为、显微组织、维氏硬度和耐磨性。维氏硬度和耐磨性被发现增加与WC体积分数在0- 90%的范围内。熔覆层组织可分为亚共晶（0-40%WC）和过共晶（50-100%WC）两个区域。
A Nd:YAG laser robot cladding system, which combines a 6-axis robot, powder supply equipment and special powder delivery nozzle has been used for a powder cladding process. The Stellite 6+WC mixed powder were clad on to mild carbon steel plate (SM400B). The depth of penetration, cracking behaviour, microstructure, Vickers hardness and wear resistance were investigated. Vickers hardness and wear resistance were found to increase with WC volume fraction in the range of 0-90%. The microstructures of clad layer can be divided into hypoeutectic (0-40%WC) and hypereutectic (50-100%WC) regions.
