Abstract: This study was directed at improving the lubricating potentials of Karanja oil (KO). KO was additivated with nano-sized MoS2 and graphene in assorted form and the experimentation was executed on a four-ball tester according to ASTM D-4172 standards. The results proved that their addition eminently brought down the wear of the test balls. Minimum wear scar diameter was recorded at 0.5% additivation which was cut down by 27.33% as compared to the virgin KO. The variation of the coefficient of friction (cof) and wear with load and speed was studied on a ball-on-disc tribometer for two different tribo-pairs. The surface characteristics of the wear scars were revealed under FESEM, optical microscope, and 3D surface profilometer. The cof and wear rate was reduced with both load and speed. This was attributed to the formation of tribo-layer on the scar surfaces as characterised by Raman analysis.
