Analysis of Tribological Characteristics of Carbon Thin Films using Molecular Dynamics

Abstract

Molecular dynamics simulation was used to investigate wear models of frictional sliding between a pin and a graphite like carbon film containing nitrogen. In this study, we developed advanced Tersoff interatomic potential describing N-N bond and C-N bond respectively. We examined the influence of content of nitride on the dynamics properties of wear atoms. These simulations show that wear is minimized when about 20 percent nitrogen is added. Also, simulation results correspond with the experimental results qualitatively.
