Study on the tribological properties of diamond and SiC interactions using atomic scale numerical simulations

Abstract

Diamond has high hardness and chemical inertness and is extensively used in friction materials. However, its wear resistance is weak in high-temperature environments and cannot meet actual requirements. In this study, the tribological properties between diamond and SiC balls were investigated at three different temperatures. Its microscopic friction and wear properties were investigated using molecular dynamics, and the simulation findings demonstrated that the diamond's wear ratio was increasing with the increase in temperature. The atomic interactions between diamond and SiC balls are understood by examining the change in stress–strain of diamond and SiC balls. This simulation findings hope to offer some theoretical reference for the industrial application of diamonds.
