Abstract

Present paper deals with investigations of electric arc discharge plasma in argon flow between Cu-Mo composite electrodes, fabricated by different technologies. The radial profiles of temperature and electron density at arc currents 3,5 and 30 A were obtained by optical emission spectroscopy. These experimental results were used in calculation of plasma composition in assumption of local thermodynamic equilibrium. Full text download
