摘　　要：研究开发了基于六自由度关节式机器人的自动化高速电弧喷涂系统。采用新研制的FeAlNbB喷涂粉芯丝材,设计优化了发动机曲轴轴颈的再制造自动化喷涂工艺,在实验室条件下测试了涂层的组织及性能,在工厂进行的批量应用效果表明,曲轴主轴颈和连杆轴颈均可实现一次性自动化喷涂,再制造的零件质量稳定,节能、节材及环保效果显著,应用前景广阔。A 6R robot–based automatic high velocity arc spraying system was developed in this study. The remanufacturing process of engine crankshaft was designed based on the newly developed automatic spraying system and the FeAlNbB cored wire. The microstructure and properties of the coating prepared were investigated in lab. The results of industrial application in engine cylinder bodies shows that, both of the main shaft manetons and the crank manetons of the crankshaft can be deposited of coating in only one procedure using the developed automatic spraying technology, and a reliable quality of the remanufactured part was obtained. Furthermore, this technology has several advantages such as energy and material saving, and environmental protection, a wide application foreground for this technology is therefore performed.
