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.
