Transition of friction properties and failure mechanisms of metal-impregnated carbon strip induced by competition between current-induced lubrication and arc erosion under varying current densities

With the increasing speed of high-speed railways, elevated current-carrying density exacerbates wear failure of metal-impregnated carbon strips in the pantograph-catenary system. This study focuses on the competitive interaction between current-induced lubrication and arc erosion...
