Development and research of metal-cladding additive to lubricants

The article indicates that one of the directions of increasing the wear resistance of rubbing parts of machines and equipment, reducing friction losses and temperatures in the friction zone is the use of special metal-plating additives to lubricants. The Engineering Center of the Timiryazev Academy has developed an experimental metal-cladding additive under the code name “MP-21” based on a mixture of fatty acids (oleic, stearic, linoleic) and plastic metal salts of the same fatty acids. The tribotechnical properties of lubricating compositions with various additives in recommended concentrations were investigated on a modernized Timken-mashine friction machine in a steady state using samples from real rolling bearing assemblies. It has been established that the developed metal-cladding additive “MP-21”, along with the additive Renom Engine, provides maximum antiwear properties and allows to reduce the wear of rubbing samples in comparison with other investigated additives from 30% to several
