摘    要:采用粉末冶金方法在相同的工艺条件下制备纯铜和碳纳米管含量为10%(体积分数)的铜基复合材料。在一种销盘式载流摩擦磨损试验机上考察了不同电流条件下2种材料的载流摩擦磨损性能。结果表明:纯铜和铜基复合材料的摩擦系数和磨损率均随电流的增大而增大,但是电流对纯铜材料的影响更加显著;纯铜材料的主导磨损机制是电弧烧蚀磨损,而铜基复合材料的主导磨损机制是塑性流动变形;碳纳米管可以改善铜基复合材料的载流摩擦磨损性能。

关 键 词:碳纳米管铜基复合材料  纯铜  载流  摩擦学性能

Abstract:Cu matrix composite reinforced with 10%(volume fraction) carbon nanotubes(CNTs/Cu) and pure Cu bulk were prepared by powder metallurgy techniques under the same consolidation processing condition.The effect of electrical current on tribological property of the materials was investigated by using a pin-on-disk friction and wear tester.The results show that the friction coefficient and wear rate of CNTs/Cu composite as well as those of pure Cu bulk increase with increasing the electrical current without excep...
Keywords:CNTs/Cu composite  pure Cu bulk  electrical current  tribological property
