Effect of Temperature on the Tribological Performance of MoS2–TiO2 Coating Material

Abstract

Recently, there is a growing interest in molybdenum disulphide (MoS2) to use as a solid lubricant to enhance the tribological properties. In the present work, composite MoS2/TiO2 coatings were prepared and bonded on pre-treated steel substrate. The manganese phosphating process has been used as a pre-treatment which helps to improve the bond strength. The coating has been bonded onto the phosphated substrate using sodium silicate as a binder. A comparative study of these composite coatings was done at different temperature, load and speed conditions using pin-on-disc tribometer. The results depict that the tribological performance such as friction coefficient and specific wear rate has been improved by coating material as compared to uncoated material.
