The experiment on the friction and wear of the lithium grease is done by choosing the ZrO2 nanoparticles as the additive in order to study the change of the tribological property of the lithium grease. The friction coefficient decreases by over 30% if the ZrO2 nanoparticles with the mass fractions of 0.25% and 0.5% are used as the additive. The ZrO2 nanoparticles with the mass fraction of 0.25% and 0.5% reach the best result and the wear scar diameter can decrease by 48.8% and 46.5%, respectively.
