Theoretical Study on Tribological Mechanism of Solid Lubricating Films in a Sand-Dust Environment

摘要

A model based on energy dissipation was developed to describe the tribological behavior of solid lubricant films in sand-dust environment. A relationship between wear rate and coefficient of friction was obtained. Theoretical results kept well consistent with the experimental data in reported publications (Qi et al., Tribol Lett 38:195-205, 2010; Surf Interface Anal 43:836-846, 2011; Wear 271:899-910, 2011). It was pointed out that the absolute value of slope of the simulated straight line is closely related with mechanical properties of solid lubricant films. The results increased our understanding about the individual friction and wear mechanism for solid lubricant films in sand-dust environment.
