Abstract
Current-carrying sliding tests of sintered Cu/Graphite composite were conducted at 80Â A and 20Â m/s. The dynamic variation of arc discharge captured by a high speed camera revealed a migrating behavior of arc discharges along the sliding direction, and this, in turn, caused an aggravated erosion of worn surface, as consistently proved by SEM, EDS and 3D characterizations. Based on the erosion mechanism, arc discharge induced material erosion could be alleviated by various means, including inhibiting migration of arcs by proper surface modification and employing functionally gradient materials (from mechanical wear resistant to arc discharge erosion resistant) in current-carrying sliding conditions.
