Synthesis and Tribological Behaviors of SiO₂/SnO₂ Composite Nanoparticles in Rapeseed Oil

Abstract:

SiO₂/SnO₂-complex nanoparticles were prepared making use of a chemical method. The tribological properties of the resulting complex nanoparticles as an additive in rapeseed oil were evaluated using four–ball friction testers. The topographies and the chemical species of the worn surfaces of steel ball were analyzed by a scanning electron microscope (SEM) and an X-ray photoelectron spectroscope (XPS), respectively. It was found that the complex nanoparticles as the additive contributed to greatly improve the anti-wear ability and load-carrying capacity of the rapeseed base oil. The improved anti-wear ability and load-carrying capacity of the base stock in the presence of the complex nanoparticles as the additive were attribute to the adsorption and deposition of the nanoparticles on the sliding surface and subsequent formation of a boundary lubricating layer with a small shearing strength.
