In this study, the as-cast Cu-10Sn-1P alloy was subjected to multi-pass (1–3 passes) accumulative back extrusion (ABE) process. Also, the effects of the process were investigated on microstructure and dry sliding wear behavior. The results indicated a significant decline in the coefficient of friction (COF) and wear rate of processed samples. The enhanced tribological properties was attributed to the microstructural adjustment, as well as improved hardness and wear active mechanism to change from adhesive/severe abrasive wear to a combination of oxidation and mild abrasive mechanisms.

通过累积反挤压（ABE）工艺提高铸态Cu-10Sn-1P合金的耐干滑磨损性能

在这项研究中，铸态的Cu-10Sn-1P合金经过多道次（1-3次）累积反挤压（ABE）工艺。同样，研究了该工艺对微观结构和干滑磨损行为的影响。结果表明加工后的样品的摩擦系数（COF）和磨损率显着下降。摩擦学性能的提高归因于微结构的调整，以及改进的硬度和磨损主动机制，从而从粘合剂/重度磨料磨损变为氧化和轻度磨料机理的结合。
