| Abstract: | The friction and wear experiments on EN31 are carried out with blends of pongamia (Pongamia pinnata) and jatropha (Jatropha curcas) with mineral oil and also conventional petroleum oil using a pin-on-disc tribometer at various loads and sliding distances. A significant drop is observed with 15% addition of pongamia and jatropha in comparison to mineral oil, for the complete tested sliding distances and loads, leading to the potential use of vegetable oil in tribological applications. To understand the lubrication regimes, a Stribeck curve is also drawn. Both pongamia and jatropha having 15% addition showed a reduction in the boundary lubrication regimes, contributing to a former start of full film lubrication. |
