Abstract

A carbon current collection brush having improved wear characteristics and exhibiting a relatively low coefficient of friction at its sliding contact surface (e.g., with a commutator or slip ring) is made by impregnating a brush blank with a solution containing an organometallic compound and an organic resin. The thereby impregnated brush blank is then cured to remove volatiles and retain approximately one to nine percent, by weight, of the organometallic compound and the organic resin in the brush blank.
