Nanoparticles as additives to lubricating oils possess excellent tribological properties,which have better dispersion stability and lubricity in lubricating oil. Nanoparticles show better friction-reducing and antiwear ability and are more suitable for the situation of heavy load and long time running, which have important roles in lower tribology as lubricants. This article introduces the preparation and application situation of nanoparticles as lubricating additives, summarizes the tribological properties and mechanism of all sorts of nanoparticles as lubricating additives and proposes the problems for further research on nanoparticles as lubricating additives.
