Study on tribological performances of MoS 2 coating at high temperature

Abstract

Molybdenum disulfide (MoS₂) is widely used as a solid lubricant. An investigation of the tribological performances for MoS₂ coating deposited on the matrix (GCr15 steel) was conducted at high temperatures. Then the effects of the applied loads and rotating speeds at transition temperature are analyzed. Experimental results show that when the temperature is lower than the transition temperature, the MoS₂ coating has excellent lubricating properties. The oxidation of the MoS₂ coating is mainly affected by the testing temperature, followed by the testing time. At the transition temperature, the increase in the applied load and rotating speed of the disc in a certain range enables the formation of MoS₂ transfer film, and improves the tribological performance of the MoS₂ coating.
