Thermal Plasma of Electric Arc Discharge Between Cu-Cr Composite Electrodes
Keywords:optical emission spectroscopy, plasma of arc discharge, erosion of surface electrode, composite materials, electrical contact
AbstractThis work deals with investigations of model plasma source realised as electric arc discharge in gas atmosphere between Cu-Cr composite electrodes. Radial distributions of temperature and electron density in arc plasma column were studied by optical emission spectroscopy. The content of electrode metals' vapours in discharge was calculated on the base of experimentally obtained plasma parameters as initial data. So, in this way the erosion properties of such composition can be determined.
