Influence of Electric Current on the Temperature Rise and Wear Mechanism of Copper-Graphite Current-Carrying Friction Pair

Yuankai Zhou et al.

Summary: The influence of current on the temperature rise and wear mechanism of the copper-graphite friction pair was studied using pin-disc current-carrying friction experiments under different current conditions. The results showed that the temperature of the friction pair increases with current, and the main wear mechanism changes from material spalling to melt ejection and arc erosion. Changes in the lubricating film led to complex wear behavior.

Study on current-carrying friction and wear properties of copper-graphite brush material reinforced by organosilicon

Xueyang Lin et al.

Summary: The brush materials modified with organosilicon prepared by the powder metallurgy method showed advantages in friction and wear properties. Organosilicon can reduce the wear rate and control the graphite content on the friction surface, but may increase adhesive wear of the materials.
