Abstract :
The electric arc in gas-metal atmosphere appears in many applications. Determining of metal vapor density in plasma is essential for mathematical modeling of plasma behavior as a conducting medium. This paper deals with investigations of arc plasma in complex gas-metal vapor mixtures. Experimental techniques in the diagnostics were presented. Various detecting materials were analyzed and advantages of using copper have been shown. Spectroscopic measurements of electric arc temperature profiles are discussed. Plasma composition has been calculated and compared to the measured results.
