The aim of the work is to establish the physical processes that take place during the interaction of thermal plasma with the surface of Cu-W composite materials. Research methods - optical emission spectroscopy. In this work, the properties of arc discharge plasma between composite Cu-W electrodes were investigated by optical emission spectroscopy methods. Electrodes made of composite materials W-Cu50 vol.% And WC-Cu50 vol.% By pressing technology at temperatures of 750, 850, 900, 950 and 1050 ° C are considered. The time and space integrated spectra of discharge plasma radiation with impurities of copper and tungsten vapors, realized due to the thermal action of the arc discharge on the surface of each of the presented electrodes, are registered and processed. The selection of the Cu I and W I spectral lines is provided. The Boltzmann diagrams were used to determine both the average time and space temperature of the plasma and its radial distributions in the middle section of the discharge channel.  Product Description popup.authors Ivanisik Anatoliy I.
