From the perspective of frictional dissipation, this study explores the law governing the wear of graphite/WC-Ni friction pair and the frictional dissipation energy of the friction pair under dry friction, and establishes the relationship between graphite wear and the frictional dissipation power of the friction pair. The results show that there is a significant linear correlation between the wear rate of graphite under dry friction and the frictional dissipation power of the friction pair. Wear prediction tests conducted under single and combined working conditions demonstrate that the developed graphite wear model can accurately predict the graphite wear amount under various working conditions, with the predicted results matching well with the actual measured values. The quantitative relationship between graphite wear rate and frictional dissipation power under dry friction features clear physical significance, convenient application, and reliable outcomes. The research findings hold important theoretical significance and engineering application value.
