Essay

Plasma parameters were investigated by optical emission and linear laser absorption spectroscopy techniques. Air, argon and carbon dioxide flows were used as working gases. It was shown, that gas flow of 6 l/min does not effect on the plasma state deviation from LTE at arc current 3.5 and 30 A. It was found that plasma state of electric arc discharge in carbon dioxide flow of 6 l/min is in LTE only at arc current 3,5 A, and at arc current 30, 50 and 100 A is not in equilibrium. Calculation of plasma composition was carried out using two temperature model.
