Friction and Wear Properties of Copper/Carbon/RB Ceramics Composite Materials under Dry Condition

In order to realize reducing wear of both overhead wires and pantograph sliders, the authors have developed new composite materials for pantograph sliders by using hard porous carbon materials “RB ceramics”. The new composite materials were developed by sintering compounds of cop...
