Study on Current-Carrying Friction Characteristics and Corrosion Resistance of Carbon Brush/Collector Ring by Copper–Graphene Electrodeposition Process

The collector ring/carbon brush assembly of a hydrogenerator set is a critical component for transmitting excitation current into the self-exciting winding. Its operating environment necessitates excellent corrosion resistance and current-carrying frictional properties. The surface condition and mat...
