The article deals with the wear of the material of the wheel flange of the car when the train enters the curved section of the track. Some types of additives are presented and tested for wear in laboratory conditions. It has been found that the use of certain types of additives reduces the wear of the rail - flange friction pair. The release of diffusion-active hydrogen from the friction zone is shown. The results obtained allow us to assert that additives based on sulfo compounds contribute to a decrease in the wear of the friction surface of the ridge and lead to a decrease in the release of diffusion-active hydrogen from the friction zone.
