| Abstract | 分别利用微米MoS2和MoS2纳米片制备出聚α烯烃基合成空间润滑脂，利用空间摩擦磨损试验机考察了两种形态的MoS2对空间润滑脂的真空高温摩擦学性能的影响。利用原子力显微镜考察了磨损表面的形貌，并采用X射线光电子能谱仪(XPS)表征了磨损后的表面元素与价态，探讨了其摩擦磨损机理。结果表明：在真空高温条件下，MoS2纳米片比微米MoS2更能改善空间润滑脂的摩擦学性能。MoS2纳米片可以在摩擦表面发生摩擦化学反应，形成润滑保护膜，降低摩擦磨损。 |
| Other Abstract | The tribological properties of PAO-based space lubricating grease containing MoS2 with different sizes and morphologies were evaluated using a Space-tribometer. The morphologies of the worn surfaces were observed by Atomic Force Microscope. Both elements and valence states on the worn surface were analyzed using X-ray photoelectron spectrometer. The results showed that nano-ball MoS2 was not suitable to act as antiwear and antifriction additive in PAO-based space grease. The nano-slices MoS2 was better than micro-MoS2 in space-tribological properties under vacuum and high temperature. The nano- slices MoS2 took place tribo-chemical reaction on the rubbing surface and formed lubricating film, and then reduced the wear. |
