Original Abstract
This paper deals with the net emission coefficients of radiation of air thermal plasmas with admixtures of copper and tungsten as a function of the plasma temperature up to 25 000 K and the arc radius (0.01 to 10 cm) at various pressures. The net emission coefficients are calculated for various equilibrium compositions (mole fractions of Cu and W) of the plasma. Calculations take into account continuum and line radiations, and special attention has also been paid to the fraction of radiation that is below a threshold of 120 nm. From the results it follows that the presence of metallic vapour increases the net emission coefficients even at low temperatures below 10 000 K.
