An electric discharge of direct current between the jet anode and the metal cathode is studied in the processes of local surface treatment of metal products at atmospheric pressure. The oscillations of the current and voltage of the discharge, the power invested in the discharge are investigated. The surface temperature of the medium in the combustion zone of the discharge was investigated. The microrelief of the product surface was studied before and after electrolyte-plasma treatment.
The types and forms of combustion of electric discharges of high-frequency (HF) current with liquid and solid electrodes at atmospheric pressure are investigated. The discharge emission spectrum, plasma composition, electron concentration, and temperature of the heavy component are studied. Thermograms on the surface of liquid and solid electrodes during the combustion of the discharge are investigated.
The low-temperature plasma of direct current electric discharges in the process of surface treatment of a product investigated. The types and forms of discharge burning investigated. The electric parameters of the discharge, oscillations of the current and voltage of the discharge, the power invested in the discharge investigated. The temperature distributions of the electrodes in the combustion zone of the discharge investigated. The composition of the discharge plasma, the electron concentration, and the rotational and vibrational temperatures of the heavy components are studied. The micro relief of the surface of the product studied before and after electrolyte-plasma treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
