Abstract

Abrasive wear of steel-aluminium tribo-pair is one of the major problems in engineering applications. In this research study, our main objective is to find out the tribological behaviour of shaft material, usually made of hardened EN8 and EN24 steel under lubricated condition against Aluminium alloy 6061. A conventional lubricant SAE 20W50 has been used, as it is the most common lubricating oil used in IC engines. Tribological tests were conducted on reciprocating friction test rig using pin-on-disc configuration under various operating parameters such as speed, load and temperature. The effect of these parameters on friction and wear was studied. It was observed in this study that with increase in load and speed, the coefficient of friction decreased while it increased with increase in temperature. However, comparison of results revealed that with the increase in load, EN24 alloy is suitable than the EN8 steel with coefficient of friction as deciding factor. The specific wear coefficient and wear volume increased with increase in all of these parameters and it was observed that under varying speed the tribo-pair consisting of EN24 steel is more suitable in comparison to EN8 steel from the wear point of view.
