Abstract

This chapter presents the lubricating properties of different vegetable-oil-based nanofluids through a comparative evaluation between frictional test and grinding experiment. The first experiment aimed to prejudge the lubricating properties of different nanofluids with a frictional test, which simulated the interface state of grinding between the abrasive grains and the workpiece. The second aimed to test and verify the lubricating properties of the same nanofluids through a grinding experiment. The mechanism of oil-film formation of nanofluids in the grinding zone was analyzed by morphology and element analysis of the worn surface. The experimental results show that Al2O3 nanofluids have the best tribological properties. Compared with pure base oil, the friction coefficient is reduced by 20%, and the optimal friction surface morphology is obtained. The good anti-friction and anti-wear properties of nanofluids are attributed to the formation of the protective oil film formed by chemical reaction on the surface.
