Study of Anodic Phenomena for Arc Plasma(Physics, Process, Instrument & Measurement)
Search this Article
Analysis of gas-tungsten-arc plasma spectra has been made by the use of monochromator, and from the distribution of spectra the local thermodynamic equilibrium (LTE) of the plasma is discussed. The spectral line of the anodic and cathodic elements were observed near the electrode. The line spectra of anodic element can be detected only near the anode. The effect of polarity were also investigated. In case of electrode positive (EP) many spectral lines were observed even in plasma column. It is concluded that the electrode polarity has an important effect on the vaporization.
