Abstract

An effective theoretical-experimental approach to evaluation of wheel steels resistance to contactfatigue damage (spalling) formation by pitting mechanism is proposed. On the base of the results of experimental studies and calculations, the contact-fatigue life curve of high-tempered 65? steel is built. The results are similar and compared to a model low-tempered 75???? steel.
