摘　　要：对活塞杆摩擦焊接头热处理工艺进行了设计和实验验证,并结合热处理后接头的显微组织观察、拉伸性能测试、拉伸断口分析等,分析了热处理(调质处理)工艺参数对焊接质量的影响,确定了焊件热处理的最佳工艺参数是:870℃加热,零保温淬火,520℃×140 min回火。The heat treatment process of piston rod friction welded joint was designed and verified by orthogonal experiment. The effects of heat treatment process on the quality of the piston rod friction welded joint were studied by microstructural observations, tensile test and fracture analysis of the welded joint material. Based on the experimental results and the analysis, the optimum process parameters of heat treatment can be summarized as follow：the quenching process is 870 ~Cx 0 min, the tempering process is 520 ℃× 140 min.
