  • Gas shrouded electrode for a plasma carburizing furnace
    Patent number: 5059757
    Abstract: An electrode for a plasma carburizing furnace is disclosed which is adapted to provide a dynamic gas shroud for inhibiting the buildup of carbon soot on the insulating elements of the electrode. The reduction of carbon soot buildup on the insulating components dramatically reduces the frequency of electrical short-circuits across the insulating component, thereby increasing the availability of the furnace for processing of workpieces.
