用金相方法研究了离心铸造双金属耐磨套简热处理前后的显旺组织变化，并对双金属耐磨套筒复合面的结构和物理特性进行了研究。通过研究双金属耐磨套筒热处理的物相变化趋势，给出了最佳热处理工艺。
The microstructure evolution of centrifugal cast bimetal wear sleeve before and after heat treatment was studied by metallographic method. The structure and physical properties of bimetal wear sleeve composite surface were studied. By studying the phase change tendency of bimetallic wear-resistant sleeve heat treatment, the best heat treatment process is given.
