The object of research is the plasma of electric arc discharges between asymmetric one-component electrodes - copper and nickel.
The purpose of the work is to deepen the understanding of the behavior of thermal plasma with impurities of copper and nickel vapors.
Research methods – optical emission spectroscopy, diagrams Boltzmann, absolute intensities.
A description of the results of research carried out at the Department of Physical Electronics of the Faculty of Radiophysics, Electronics and Computer Systems of Taras Shevchenko National University of Kyiv in accordance with the order of the Ministry of Education and Science of Ukraine dated 04/07/2022 No. 317 "On financing joint Ukrainian-French research projects" is given in in 2022".
In this work, the radial distributions of plasma parameters with impurities of copper and nickel vapors in different cross-sections of the discharge channel, namely: in the positive column and near-electrode areas, were investigated using the methods of optical emission spectroscopy. The plasma temperature was determined by the diagram method Boltzmann with the involvement of the emission intensity of the spectral lines of both copper and nickel atoms. Concentrations of various kinds of metal atoms of electrode origin were determined by the method of absolute intensities corresponding spectral lines of radiation of such plasma.
