Anti-frictional lubricant additives for locomotive wheel flange

The article deals with the material wear of the car wheel flange 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 using certain types of additives reduces wear of the rail-flange friction pair. Releasing diffusion-active hydrogen from the friction zone is shown. The results obtained allow us to assert that additives based on sulfo compounds contribute to decreasing the wear of the flange friction surface and lead to decreasing the release of diffusion-active hydrogen from the friction zone.
