The purpose of the work is to determine the scientific foundations and develop a system of principles for the production of highly effective two-phase oil-vapor-gas lubricating materials on the basis of fundamental theoretical and experimental studies of phase transitions in boundary layers in the course of friction. Research methods - the method of differential-phase profilometry and profilography for determining the volumetric and spatial microgeometry of working friction surfaces; X-ray spectral method for evaluating the physico-chemical properties of friction surfaces; laboratory methods for studying the working parameters of model tribosystems on test instruments and friction machines. The design development of roller rolling assemblies for the main reducers of the high-powered TV3-117VMA-SBM1 the implementation of the lubricant with engines has been introduced, namely a two-phase oil-vapor-air suspension leads to a significant increase in their life without signs of fatigue dyeing of the rolling surfaces (from 415 to 1000 hours). The completed design improvement was implemented on eight TV3-117VMA-SBM1 engines, which are currently in operation. The main provisions of the adhesion-hydrodynamic (AGD) theory and the foundations for the formation of highly effective oil-vapor-gas lubricating materials have been developed. The scientific foundations and principles of production of highly effective two-phase oil-vapor-gas lubricating materials are determined.
