Abstract :
New copper-graphite brushes lined with porous copper have been developed and tested. The new brushes are produced by applied powder metallurgy. They can absorb the vibration caused by sliding friction. The friction coefficient, specific wear rate, and contact voltage drop for the new brushes are superior to those of conventional ones without lining.<>
