Abstract: The application of SiO₂ nano-particles as lubricating oil additives is still in the initial process, while it possesses excellent tribological performance according to the results of test. The method of surface modification of SiO₂ nano-particles, research development of SiO₂nano-particles as lubricating oil additives and its acting mechanism were discussed. The direction of research in this field, such as “one-step”of preparation and surface modification of SiO₂ nano-particles, study on the polymer- SiO₂ inorganic hybrid nano-particles and acting mechanism of SiO₂ nano-particles, was pointed out.
