Abstract: The tribological properties of Lithium grease specimens with different concentrations of Al<subscript>2</subscript>O<subscript>3</subscript> nanoparticles were investigated using a pin on disc apparatus under different sliding speeds and normal loads. Results showed that Al<subscript>2</subscript>O<subscript>3</subscript> nanoparticles enhanced the tribological properties of lithium grease and reduced the COF and wear scar width by approximately 57.9% and 47.5% respectively.
