Electrical Discharge between a Metal Cathode and a Liquid Non-Metal Anode

Gas-discharge plasma generated between a metal cathode and a liquid non-metal anode at atmospheric pressure was studied. The discharge was ignited by submerging the metal electrode in the electrolyte. The types and shapes of the plasma structures generated in the interelectrode gap were considered, as well as their electrophysical parameters. The results of the thermographic analysis of the electrode surface are presented during the burning of the discharge. Emission spectroscopy was used to study the plasma composition, the electron density, and the temperature of the heavy component.
