  • 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 MoS2) imparted life ability and electrical voltage stability comparable to those of present-day industrial grade brushes operating in normal air atmospheres.
