Friction and Wear Behaviors of Copper Rubbing against Carbon Material with and without Windy Conditions

Abstract:

An experimental study on friction and wear properties of carbon strip rubbing against copper contact wire was carried out on a pin-on-disc frictional tester with and without windy conditions. The result shows that wear rate of pin specimen increases observably with increasing sliding distance with and without windy conditions. While the coefficient of friction slightly decreases with increasing of electric current with and without the wind. Observing the SEM morphology of pin specimens, it can be found that delamination wear is a main wear mechanism under no windy condition. While arc erosion is a dominant wear mechanism with windy condition. Worn surfaces of the materials were analyzed by an energy dispersive X-ray spectroscopy. It can be observed that oxidation wear occurs in the frictional process due to arc erosion and high temperature rise.
