Abstract

The results of triboengineering tests have revealed the effectiveness of β-sialon nanodispersed particles as an additive to lubricating materials oiling heavily loaded friction units. The method of X-ray structural analysis has established that use of β-sialon as an additive leads to the appearance of steel structures in the surface layer distinct in having a larger parameter of the crystalline lattice, reduced relative mean quadratic micro-deformation, and sparser dislocations, ensuring better triboengineering characteristics of friction couples. The main tribological effect of β-sialon in the lubricating material is that the mechanical energy of deformation converts into the chemical energy of formation of a new structure—an ordered surface layer.
