Abstract


The structural and chemical changes near the tread surface of the railway wheels with the different tread profiles during operation were investigated. The influence of the structural changes in steel on forming of the micro-destructions and tread wearing was determined. The advantages of the complexcurvilinear tread surface were shown.


Keywords
