摘 要：A type of additive-SiO2/ZnO combined nanoparticle were obtained by chemical method. The tribologica land repairing properties as lube additives have been studied by four-ball tester and ring-on-block tribotesters. The morphographies of the worn surfaces were analyzed by means of scanning electron microscopy(SEM). The results show that the additive possesses excellent extreme-pressure( EP), anti-wear(AW) , friction reducion and self-repairing properties. The lubrication and repairing mechanism is inferred that SiO2/ZnO combined nanoparticle is sedimented on the surface of steel, the lower surface film is formed under the high temperature and high pressure. The film possess excellent anti-wear , friction-reducing and repairing properties.
