Plasma of arc discharge between melting Cu- and Ni-electrodes
The intensity of erosion processes of asymmetric single-component Cu and Ni electrodes of the free burning electric arc at current of 30 A is studied by measurements of a content metals vapour in plasma column. Optical emission spectroscopy was used to determine the radial distributions of plasma...

Digital Library of Periodicals of National Academy of Sciences of UkraineРезюме: | The intensity of erosion processes of asymmetric single-component Cu and Ni electrodes of the free burning
electric arc at current of 30 A is studied by measurements of a content metals vapour in plasma column. Optical
emission spectroscopy was used to determine the radial distributions of plasma temperature and electron density in the
middle section of a discharge gap. These experimentally obtained data were used in the calculation of equilibrium
plasma composition. So, the evaporation intensity of each electrode material can be estimated in such indirect way. |
