摘    要:用压制和烧结的方法,制备了纳米Al2O3和聚四氟乙烯(PTFE)的复合材料。研究了纳米Al2O3粒子对PTFE的摩擦、磨损、硬度、耐冲击强度等性能的影响。结果表明:纳米Al2O3粒子不仅显著地提高了PTFE耐磨性,而且降低了PTFE的摩擦系数,同时使PTFE的硬度增大。对作用机理进行分析和探讨,提出了“纳米粒子在摩擦磨损表面产生富积及重新嵌入“的观点,为材料的改性研究提供参考。

关 键 词:工程材料  聚四氟乙烯  性能  纳米氧化铝

Abstract:The composite material of nano Al 2O 3 and polytetrafluoroethylene (PTFE) was made by the process of pressing and sintering. Effect of nano Al 2O 3 on the friction and wear characteristic of PTFE plastic was studied. At the same time, the hardness of PTFE was measurated in sclerometer. The results showed that nano Al 2O 3 not only decreased the friction coefficient of PTFE, but also greatly reduced the wear of PTFE. And the hardness of PTFE was improved. It proposes the idea of enrichment and re inset in friction and wear surface.
Keywords:nano  Al  2O  3  PTFE  property  effect
