摘要:
The invention relates to a carbon brush (10) having a metal layer (16, 18) on at least one surface area (12, 14) of the carbon brush. In order to provide a metal layer exhibiting good heat-dissipating properties, the invention provides that the metal layer is a metal conductive paint layer (16, 18).
摘要:
The invention relates to a resin bonded graphite material which is especially suitable for use as an electric contact. The invention also relates to a method for the production of a resin bonded graphite material especially for use as an electric contact material. The invention further relates to the use of a resin bonded graphite material. The aim of the invention is to develop a corresponding resin bonded graphite material in such a way that interference is excluded or almost excluded when used as an electric contact. According to the invention, the resin bonded graphite material is made of a hardened mixture of electrographite containing carbon black, the carbon black content RG being >/=30 wt. %, electrographite devoid of carbon black and a bonding agent and a specific electric resistor Wspez being >/= 3.500 mu omega m.
