  • Method for joining graphite to graphite
    Patent number: 4382113
    Abstract: A method of joining together a plurality of graphite members providing a low transition resistance is described. The method includes the steps of interposing a layer of a thermally sensitive material between the graphite members to be joined, applying pressure to force the graphite members together, applying sufficient heat to melt the thermally sensitive material, and releasing the pressure after providing a period of time for cooling. The thermally sensitive material is preferably composed from a thermoplastic material, and the heat for melting this material is preferably provided by resistance brazing.
