| 摘 要： | 在模拟空间原子氧与高真空条件下，分别对微米MoS2、MoS2纳米球与MoS2-IC 3种复合润滑材料的摩擦学性能进行了测试。结果显示MoS2纳米球复合材料具有最优的抗磨性能，MoS2-IC复合材料的抗磨性能次之，微米MoS2复合材料最差。3种复合材料的减摩性能相差较小，MoS2纳米球复合材料的摩擦系数仅比其他两种复合材料略低。MoS2-IC具有较高的化学活性，在摩擦过程中发生转移并形成转移润滑膜，从而具有较优的抗磨性能，MoS2纳米球优异的摩擦学性能与其独特的球形封闭结构相关。

| Abstract: | Under simulated space conditions such as atom oxygen and high vacuum,the tribological properties of the composite materials of micro-MoS2,MoS2 nano-ball and MoS2-IC are studied in this paper.The results show that the composite material of MoS2 nano-ball has the best anti-wear properties.The MoS2-IC has also a good wear resistance,while micro-MoS2 is the worst regarding the wear resistance.However,they are not very much different with respect to the friction reducing performance,with MoS2 nano-ball showing o... |
