ABSTRAKT

Work gives model and results of calculating the cathode processes of the Arc plasma torches at atmospheric pressure with the thermal cathodes. Calculations were performed on the basis of the method of integral balances for the cathode made of the pure tungsten W and the thoriated tungsten W(2% ThO2) over a wide range of temperatures of cathodes (Tk = 3000 − 4400 K for W and Tk = 2000 − 3200 K for W(2% ThO2)) and argon plasma (Te = 20000 − 40000 K).
