Abstract
Molybdenum disulphide (MoS2) is widely used in various applications because of its lubricating properties. However, its performance needs to further improve. In the present work Molybdenum disulphide (MoS2) based composite coating with addition of TiO2 (having different particle size and weight% addition) were developed and coated on AISI52100 steel substrate. The substrate specimens were pre-treated using phosphating to improve the porosity which helps to enhance the bond strength between the coating and steel substrate. A tribological study of this developed composite coating was carried out at different contact pressures and sliding speeds using the pin-on-disc test rig. It was observed that particle size of TiO2 and its different wt% significantly affects the tribological properties of the developed composite coating. In case of all considered operating conditions with developed samples of composite MoS2-TiO2 coating, the sample C (63.3 nm particle size with 15 wt% addition) of TiO2 depicts about 31% lower coefficient of friction and 39% lower wear rate compared to pure MoS2 coating.
