Abstract

In recent decades appeared the considerable interest in the use of the antiwear, anticorrosion and restoration technologies in friction units, including the internal combustion engines. These technologies allow reducing the friction coefficient and the wear of friction surfaces during the operation without disassembly of the components and assemblies. The present work involves the studies of the tribotechnical characteristics of the friction pairs when using the antiwear antifrictional (AWAF) composition, injected in the lubricating medium. The results show, that injection of the AWAF composition in the lubricating material does not cause the changes in the microstructure and microhardness of the surface of friction pairs, friction coefficient decreases in 1.5 ? 2 times, the amount of wear of the rubbing parts is close to zero. The obtained effect is causes by the establishing of the selective transfer process (wearless friction) with the formation of the servovite film. Application of this composition allows to improve efficiency of machines and equipment, considerably reduce the content of CO and CH as well as solid impurities in the engine exhaust gases, and reduce the running-in time of the diesel engines.
