Cathode diameter and operating parameter effects on hafnium cathode evaporation for oxygen plasma cutting arc

Evaporation of hafnium cathode in a plasma cutting arc torch was investigated numerically and experimentally to assess the effects of cathode diameter and operating parameters such as gas pressure, gas flow rate and arc current. A numerical model was developed for arc plasma with consideration of ha...
