Abstract

The wear mechanism of railway wheel with cone-and-plate profile of tread surface is investigated. It is established that repeated cyclic thermomechanical influence on a tread surface under operation leads to accumulation of stresses and defects, which results in formation of wear particles having the various form, source and mechanism of formation.
