Tribological Performance of AlN Nanoparticles as Lubricating Oil Additive

Abstract:

By using Four-ball test machine, the anti-wear and extreme pressure performance of the lubricating oil that contain the ceramics nanoparticles additives were investigated. With the help of scanning electron microscopy (SEM), the worn surface is observed, and its tribological performance is studied. The experimental results show that nanoparticles additives can effectively improve extreme pressure and anti-wear performance of the lubricating oil, and the optimal concentration of it in the base oil is 3 wt%. With ZDDP additive contrast experiment show that under low-load and long time conditions, ZDDP additive is far inferior to nanoparticles additives, and containing AlN nanoparticles additives lubricating oil mainly happen Fatigue wear and scratch.
