| Abstract: | A method is proposed for improving the wear resistance of current collectors in high-speed electrified transport by shaping them aerodynamically. In this case, the rate of nonspontaneous topochemichal reactions with the production of negative entropy on friction surfaces increases. This helps to lower the wear rate of sliding electric contacts. |
