OPTICAL EMISSION SPECTROSCOPY OF DISCHARGE PLASMA BETWEEN ASYMMETRIC Cu AND Ni ELECTRODES
Résumé
This work deals with optical emission spectroscopy studies plasma of electric arc discharge between asymmetric copper and nickel electrodes at arc current of 3.5 A in four different modes. Namely, arc discharges were initiated at different polarities and with different electrodes' position. As an initial study, the possibility of using the Ni I spectral lines to determine the plasma temperature by the Boltzmann plot technique was investigated.
