| Abstract: | MRH-3 friction and wear tester were utilized to investigate tribological property of a mixed Al2O3-Al-MgO nano-particle additive in lithium grease.The chemical states of the substances and apperance on the friction surfaces were analyzed by STM and EDS.The results show that the mixed nano-particles additive in lithium grease can improve antifriction,reconditioned and extrem-pressure properties of the base grease greatly compared to single nano-particle addition. |
