- Abstract
In this paper, nano-Al2O3 was added to soybean oil to improve its anti-wear and anti-friction properties, and the effects of four different dispersants on the suspension stability of nano-Al2O3 in soybean oil were compared. Using HRS-2M high speed reciprocating friction tester, the anti-wear and anti-friction effects of Al2O3 nanofluid were tested. The anti-wear and anti-friction mechanism and wetting properties of Al2O3 nanofluid were studied by using probe 3D profilometer, contact angle measuring instrument, scanning electron microscope and energy spectrometer. The results showed that sodium dodecyl benzene sulfonate (SDBS) had the best suspension stability of nano-Al2O3 in soybean oil. Nano-Al2O3 could effectively improve the anti-wear and anti-friction performances of soybean oil. When the mass fraction of nano-Al2O3 was 2.0 %, the contact angle was the smallest and the anti-wear and anti-friction performances were the best. The action mechanism of Al2O3 nanoparticles was analyzed by combining EDS results. [ABSTRACT FROM AUTHOR]
