Study on the Tribological Properties of Lubricating Oils Containing La2O3 Nanoparticles as Additives
La2O3 nanoparticles were selected as additives of lubricating oils.The tribological properties of lubricating oils containing La2O3 nanoparticles were examined by MRS-1J four-ball wear tester. The results show that the lubricating oils containing La2O3 nanoparticles as addictives have good tribological properties, and the optimal quality fraction is 0.8％. The PB value increases by 40.8％, wear spot diameter decreases by 36.9％ and friction coefficient decreases by 29％, compared with 500SN base oil.
