二硫化钼与金属相摩擦可在金属表面上形成一层MoS_2转移膜。这种转移膜对润滑效果有着重要的影响。在相同的摩擦条件下,不同金属底材上的MoS_2转移膜的牢固程度不同。作者用扫描俄歇电子能谱(SAM)和扫描电镜(SEM)考察了MoS_2在不同金属表面上摩擦转移膜的硫的俄歇电子象和表面形貌,並用氨离子刻蚀技术与俄歇电子能谱(AES)联用,试图鉴别MoS_2与金属底材附着的牢固程度。最后用栓-盘型摩擦试验机评价了各种金属底材上MoS_2转移膜的耐磨性能,并与金属的硬度,金属硫化物的原子化能、金属-硫键键能进行了关联。结果说明,MoS_2的摩擦转移膜与金属底材附着的牢固程度和耐磨性都难以用物理学说解释,似乎与该金属的化学活性有关,本文简要地叙述了这些试验的结果。
Molybdenum disulfide and metal phase friction can be formed on the metal surface layer MoS_2 transfer film. This transfer film has a significant effect on lubrication. Under the same friction condition, the MoS 2 transfer films on different metal substrates have different firmness. The authors investigated the Auger Auger electron image and surface morphology of the MoS 2 trifluortetransfer film on different metal surfaces by scanning Auger electron spectroscopy (SAM) and scanning electron microscopy (SEM). The Auger electron and Auger electron (AES), attempting to identify the firmness of MoS_2 to the metal substrate. Finally, the wear resistance of the MoS_2 film on various metal substrates was evaluated by the tumbler-disc friction tester and correlated with the hardness, the atomization energy of metal sulfides and the metal-sulfur bond energy. The results show that MoS_2 friction transfer film attached to the metal substrate firmness and wear resistance are difficult to explain the physical theory, it seems that the chemical activity of the metal, the paper briefly describes the results of these tests.
