  • Electrode for vapor deposition and vapor-deposition method using same
    Patent number: 4978556
    Abstract: Thermal breakage of crystalline electrodes used in arc-vapor deposition is prevented by originally fabricating the electrodes from broken pieces of the crystalline material which are slightly sintered together and form an electrode body in which a carbon rod or other conductor is embedded to provide electrical contact. The particles are sintered in a vacuum oven and a pool of the electrode material can be formed at a working end of the electrode body when the latter is used for arc-vapor deposition.
    Type: Grant
    Filed: January 25, 1990
    Date of Patent: December 18, 1990
    Assignee: Vapor Technologies Inc.
