摘　　要：锡基巴氏合金广泛应用于轴瓦的生产和修复,ZChSnSb11-6的性能优于ZChSnSb8-4。但由于ZChSnSb11-6铸态组织中富含粗大的硬质相,其加工性能较差,本文通过优化熔炼铸造、挤压、拉拔等工序成功制备出适合热喷涂使用的锡基巴氏合金ZChSnSb11-6丝材。通过进行金相试验,显微硬度、结合强度、孔隙率等测试,满足轴瓦再制造热喷涂的要求。Tin base Babbitt alloy widely used in bearing bush production and repair, the performance of ZChSnSbl 1-6 is better than ZChSnSb8-4.But as a result of as-cast structure of ZChSnSbl 1-6 is rich in big hard phase, its processing performance is bad, in this paper, through the optimization of smelting, casting, extrusion, drawing and other processes we have been successfully prepared ZChSnSbl 1-6 wire suitable for thermal spraying. Through metallographic examination, micro hardness, bond strength and porosity testing, it was proved that the wire meet the requirements of bearing manufacturing thermal spraying.
