Investigation of Thermochemical Zirconium Cathodes in Nitrogen

For arcs with zirconium cathodes in nitrogen, experimental results are presented about changes of material and structure of the cathode, temperature fields, current densities, heat flows, electron work function and erosion rate. The cathode heat regime is described theoretically. In the experiments,...

Beschreibung
Zusammenfassung:	For arcs with zirconium cathodes in nitrogen, experimental results are presented about changes of material and structure of the cathode, temperature fields, current densities, heat flows, electron work function and erosion rate. The cathode heat regime is described theoretically. In the experiments, the arc current was 50–200 A.
