Tests were carried out to determine the wear of the surface of the locomotive wheel rail using a Puma lubricant with a sulfonic additive, with an additive of a hydroquinone derivative and an organophosphorus compound and to determine the amount of diffusionally active hydrogen released in the system. The purpose of the work was to determine the wear of the rail material and analyze the lubricant with the selected additives. The principle of action of additives and the nature of their interaction with rubbing surfaces is analyzed. Additives have been identified that reduce surface wear, as well as an additive that best binds hydrogen. As a result of the work, it was revealed that the additives of the sulfo- and organophosphate compounds reduce the wear of the friction surface, and it is also shown that the organophosphate compound reduces the release of diffusionally active hydrogen into the system.
