| 摘 要： | 作者采用冷压-烧结工艺研制了Al_2O_3+PTFE、PTFE+PPS和Al_2O_3+(PTFE+PPS)3类复合材料,并对这些材料的摩擦磨损行为及其磨损机理进行了研究。结果表明,适量Al_2O_3粒子的弥散可以明显提高复合材料的耐磨性,PTFE+PPS复合材料的耐磨性远比PTFE的好,摩擦系数几乎与PTFE的相同,是一种良好的减摩抗磨材料。复合材料的磨损过程主要受粘着、犁削和塑性流动机制的控制。

| Abstract: | Al2O3/PTFE,PTFE-PPS,Al2O3/(PTFE-PPS) composites were made by using the process of cold pressing-sintering and their friction and wear behaviors were studied. The dispersion of Al2O3(50um) particles with proper content in PTFE or PTFE-PPS matrix can obviously increase their wear resistance. PTFE-PPS composite possess excellent wear resistance and low friction coefficient. Friction and wear of these composites are controlled by following mechanisms: adhesion, ploughing, plastic flow and delamination. |
