- W4312493988 abstract "The purpose: Investigation of mechanisms of wear particles formation on railway wheels tread during operation. Methods: Causes of wear particles formation on railway wheels tread were investigated. Structural factors connecting with plastic deformation, formation of “white layer”, and also with non-metallic inclusions and corrosive products of wheel steel, defining wear of railway wheels tread during operation were fixed. Repeating heat-mechanical action on railway wheel tread by interaction between wheel and rail promotes incandescence of stresses and defects (microcracks, separations) that promote wear particles formation having different shape, source and mechanism of nucleation. Results: Results of analysis of microcracks, spalles and wear particles and also of mechanisms of their formation was shown that wear of railway wheel tread is very composite phenomenon. It passes by few mechanisms (fatigue, adsorbtional, corrosive, under friction) and is multifactors process. Practical importance: The study of the mechanism of wear of railway wheels allows not only to reduce the wear losses, but also to develop effective methods for predicting their service life, as well as to ensure their operation, especially in extreme conditions." @default.
