State Engineering Center of Hard Alloys «Svetkermet», Svetlovodsk, UkraineAbstract
An electrode and its manufacturing method are proposed, which envisage formation of a tight contact of the electrode case with the active insert during their joining. A composite material has been developed for the active insert of plasmatron electrode with a barrier layer of zirconium nitride
Keywords: plasmatrons, electrodes, active elements, cores, zirconium nitride, zirconium, operating life
