Abstract

In recent times, there is a growing interest in applying Molybdenum disulphide (MoSx) solid lubricant coatings on components to improve the tribological performance (i.e. lower friction coefficient and wear rate). The tribological performance of MoSx coating is strongly dependent on coating properties and tribological environment. MoSx coatings are highly successful in certain applications such as in space/vacuum technology, but its effectiveness is questioned in other terrestrial applications such as in cutting tool industry due to its lower hardness and poor oxidation resistance leading to shorter life. In order to circumvent this drawback, the paper identifies that current research is being concentrated on developing MoS x based coatings using three different approaches: (1) Metal or compound addition in MoSx coating (2) MoSx layer on hard coating and (3) MoSx addition in hard coating matrix. Although the primary objective is same in all three cases, the third approach is considered to be more effective in improving the tribological properties of the coating. Finally, the potential applications of MoSx based coatings in different industrial sectors have been briefly outlined. © 2010 American Institute of Physics.
