ABSTRACT:
An electrode structure used in a glow discharge system for nitride hardening of metals. The structure includes an anode plate, a cathode plate, a conductor connected to the cathode plate and an insulating dielectric shroud which surrounds the conductor. The two plates are firmly attached to the dielectric shroud so as to prevent any air gaps across which an arc may form. The shroud includes a plurality of annular grooves at one end to prevent the surface of the shroud from being covered by extraneous matter which would allow an arc to form between the plates.
