Abstract
The effects of various factors on wear mechanism of railway wheel with cone-and-plate profile of tread surface was investigated. It was established that repeated cyclic thermomechanical effect on a tread surface under operation, as well as nonmetallic inclusions and corrosion products led to accumulation of stresses and defects, which resulted in formation of wear particles having various form, source and mechanism of formation.
