초록
Friction characteristics and electrical resistance of sliding contacts in slipring-brush assembly were investigated. Four brush materials containing relative amounts of copper and graphite were studied. The result showed that a copper-graphite brush at a particular graphite content exhibited the most stable frictional and electrical behaviour suggesting an optimum amount of solid lubricant in metal-graphite brush system. Microscopic observation and the surface analysis showed good agreement with this phenomena.
