摩擦磨损的扫描电子显微镜原位动态研究，可以跟踪观察磨屑形成和磨痕演变的全过程，以及材料表面在摩擦磨损中变化的真实情况．在由国产台式扫描电子显微镜改装成的滑动摩擦磨损试验装置上，对１５＃钢－４５＃钢摩擦磨损过程所作的原位动态研究表明：１５＃钢在对摩过程中始终存在粘－滑现象，微切削是其主要磨损机理；１５＃钢磨痕形貌变化可分５个阶段——第１阶段出现与滑动方向垂直的横向裂纹，第２阶段产生大片状剥离，第３阶段产生小片状疲劳剥离，第４阶段产生块状磨屑并形成表面凹坑，第５阶段磨痕趋于平坦．这种滑动摩擦磨损试验装置不仅具有对摩擦磨损过程作动态跟踪观察的功能，而且可用于对摩擦学过程作准动态观察，这两种观察方法对研究摩擦磨损过程同等重要
Friction and wear of the scanning electron microscope in situ dynamic study, you can track the whole process of observing the formation of wear debris and wear traces, and the material surface changes in the friction and wear the real situation. In-situ dynamic research on the friction and wear process of 15 # steel-45 # steel made by domestic bench-top scanning electron microscope has shown that the stick-slip phenomenon of 15 # steel always exists during the friction process , Micro-cutting is the main wear mechanism; 15 # steel scar morphology can be divided into five stages - the first stage and the sliding direction of the vertical cracks appear, the second stage of the large flake, the third stage of small Flake fatigue peeling, the fourth stage of debris generated debris and the formation of surface pits, the fifth phase of wear marks tend to be flat. This sliding friction and wear test device not only has the function of dynamic tracking of the friction and wear process, but also can be used for quasi-dynamic observation of the tribology process. Both of these observation methods are equally important for the study of friction and wear processes
