Abstract

The tribological properties of lubricating compositions based on TSp-10 transmission lubricating oil are explored. The compositions contain highly dispersed particles of MTMS aerogel with a concentration of 0–4 wt %. It is established that the presence of these particles improves the tribological properties of the lubricant. The best parameters can be achieved with a concentration of aerogel particles inside the lubricating layer of 2.5–2.7 wt %. The frictional force is expected to be reduced by ≈33% and wear by ≈36% in comparison to the base oil. A description of antifriction and antiwear effect of the dispersed additive is provided on the basis of analysis of the chemical oxidation and decomposition reactions of the aerogel.
