本文对金刚石抛光过程中产生的磨屑进行了分析，并在高速滑动机上进行了金刚石与金刚石的快速滑动试验。通过扫描透射电子显微镜（STEM）中的电子能量损失谱（EELS）和透射电子显微镜（TEM）研究碎片。这项工作的目的是提高对抛光过程的理解。发现当在（100）平面上沿（100）方向抛光金刚石时产生的碎片由较不致密形式的碳组成。在高速滑动机的实验中发现了金刚石碎片，但磨损痕迹显示出与常规抛光后表面上观察到的明显不同的特征。结果表明，在软方向上的金刚石的抛光发生的过程中，金刚石转化为密度较低的形式的碳，然后转化的材料分离。
Experiments on the analysis of the wear debris produced during the polishing of diamond and the rapid sliding of diamond upon diamond using a high-speed sliding machine are presented. The debris was studied by electron energy loss spectroscopy (EELS) in a scanning transmission electron microscope (STEM) and by transmission electron microscopy (TEM). The aim of the work was to improve understanding of the polishing process. It was found that the debris produced when polishing diamond in a (100) direction on a (100) plane consisted of less dense forms of carbon. Diamond debris was instead found in the experiment with the high-speed sliding machine, but the wear track showed markedly different features from those observed on a surface after conventional polishing. The results suggest that the polishing of diamond in the soft directions occurs by a process in which diamond transforms to less dense forms of carbon, after which the transformed material detaches.
