A series of experimental tests were carried out using stainless steel rubbing against copper-impregnated metallized carbon under electrical current on a pin-on-disc test rig. The test parameters include the sliding speed of 60–100km/h, normal force of 40–80N and electrical current of 0–50A. During testing, the friction coefficient and wear volume were recorded. The topography of worn surfaces was...
In this paper, we developed a new tester by modifying the jigs and the control system of conventional pin-on-disc apparatus. The friction and wear characteristics of aluminum–stainless steel composite conductor rail and collector shoe used in subway third rail traction system were investigated on the tester with an electrical current applied across the sliding interface. The friction coefficient and...
