摘要

研制并试验了一种内衬多孔铜的新型铜石墨刷。新型电刷采用应用粉末冶金技术生产。它们能吸收滑动摩擦引起的振动。新型电刷的摩擦系数、比磨损率、接触压降均优于无衬里的传统电刷。

Copper-graphite brushes lined with porous metals

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.<>
