Abstract
Conventional carbon brushes developed for earth's surface applications were found to be inadequate in terms of wearing life when applied in electrical contact with copper slip rings operating in dry inert-gas atmospheres. Under similar conditions, however, the life of such brushes was vastly increased when special treatments were incorporated in their body structure. One of these treatments (40 W/o MoS 2 ) imparted life ability and electrical voltage stability comparable to those of present-day industrial grade brushes operating in normal air atmospheres.
为地球表面应用而开发的传统碳刷被发现在磨损寿命方面是不足的，当与在干燥惰性气体环境中工作的铜滑环电接触时。然而，在类似的条件下，如果在刷子的身体结构中加入特殊处理，这种刷子的寿命就会大大延长。其中一种处理(40 W/o MoS 2)赋予寿命能力和电压稳定性，可与当今在正常空气环境中操作的工业级电刷相媲美。
