二硫化钼的电子显微分析

Electron Microscopy Analysis of Molybdenum Disulfide

为了促进含ＭｏＳ２的润滑材料的应用及其基础研究的发展，利用电子显微分析技术研究了国产ＭｏＳ２的硫／钼原子比、颗粒形貌及其结构，给出了不同产地ＭｏＳ２粉末的粒径（从微米到纳米范围），以及ＭｏＳ２粘结膜和ＭｏＳ２溅射膜的形貌（由断面显示出膜的厚度），并且指出当硫／钼原子比接近于２．００时，ＭｏＳ２溅射膜的耐磨寿命最长，同时还利用高分辨透射电子显微照片和电子衍射图揭示了国产ＭｏＳ２的晶体结构及其参数。研究结果对含ＭｏＳ２润滑材料的发展及其润滑机理研究具有参考和应用价值。

In order to promote the development of application and basic study of lubricatingmaterlal containing MoS2,the atom ratio between sulfur and molybdenum elements,themicrographs and the structure of MoS2 were investigated by using electron microscopy , and then thetopographs and dimensions(from μm to nm)of MoS2 powder from the different prtxlucing area,MoS2 bonded film and MoS2 sputtered film were given out.The results shown that the wear life ofMoS2 sputtered film is the longest when the atom ratio between sulfur and molybdenum approaches2.00.The crystal structure perameters of MoS2 were revealed with high resolusion TEMmicrographs and electron diffraction patterns。
