Abstract
<jats:p>The monograph is devoted to the issue of improving the frictional characteristics of the two-point «wheel-rail» contact by the influence of the electric current on the rolling track, and the «wheel-rail ridge» contact zone by ozonated air flow. A method and a device for reducing the wear of the rim of the wheel pair have been developed, which allow creating favorable conditions for the contact of the rim of the wheels and the rails, due to the effect of ozonized air flow on their contact zone. The wear of tribosurfaces during the passage of an electric current was experimentally and theoretically evaluated, and the temperature increase in the frictional contact was estimated. The mechanism of influence of ozonated air flow on the tribotechnical characteristics of the contact pair is proposed</jats:p>
