Abstract

The present study is an endeavor to understand the wear and friction behavior of EN8 steel and Inconel X-750 alloy tribo-pair under dry and lubricated conditions. Initial experiments were performed under dry conditions at different loads (50–200 N) and sliding speeds (0.14–0.47 m/s). To investigate the effect of lubricants, the experiments were performed under two lubricants (SEA20W40 and SAE20W40 + MoS2) at the same range of loads and speeds. Ex-situ analysis of worn-out surfaces of both disc and pin was performed through scanning electron microscope (SEM). Chemical composition of worn-out surfaces of disc and pin was evaluated through energy disperse x-ray spectroscopy (EDS). Under dry conditions, formation of oxide layer was noticed. The significant improvement in wear and friction was observed under lubricated conditions as compared to dry conditions. Also, by mixing micron-size MoS2 particles to the normal lubricant SAE20W40, significant improvement in wear and friction was perceived due to the formation of boundary layer film.
