“…Yin et al [23] used a spherical diamond indenter to study the nanoscale wear behavior of SiC particle-reinforced aluminum matrix composites (SiC/Al NCs), exploring the influence of scratching depth, scratching speed, temperature, indenter size, and particle size during the nanoscratching process. Chen et al [24] used MD simulation to study the morphology of nanotwinned diamond chips, subsurface damage, temperature, and stress distribution under scratching. The study of the wear mechanism of diamond using MD has been ongoing.…”

Diamond, possessing high hardness and chemical stability, finds wide-ranging applications across various industries. However, during the friction process, a graphitization phenomenon may occur, which changes the mechanical properties of the diamond. In this study, molecular dynamics simulation was performed using SiC ball to investigate the influence of indentation depth and temperature on the graphitization transition of the diamond surface. The results showed that the dominant factor affecting the sp2 hybridization ratio during the indentation process was stress, while the temperature was the dominant factor during sliding. The results of this study can be used to understand the friction and wear behavior of diamonds and SiC ball and provide theoretical references for the industrial application of diamonds.
