In this work, the radial distributions of parameters of plasma with copper and nickel vapours admixtures in positive column of electric arc discharge were investigated by optical emission spectroscopy. The plasma temperature was determined by the Boltzmann plot technique on the basis of absolute values of radiation intensity of both copper and nickel atomic spectral lines. Concentrations of both kinds of metal atoms of electrode origin were determined by the method of absolute intensities of the corresponding spectral lines of radiation of such plasma.

This work is devoted to diagnostics of thermal electric arc discharge plasma with copper and nickel vapour admixtures by optical emission spectroscopy and possibility of its usage for investigation of plasma regions nearelectrodes surfaces. The spectra of plasma emission from such areas were obtained by registration device with spatial and spectral resolution. The Boltzmann plot technique was used to determine the radial distribution of plasma temperature of arc discharge channel in different cross-sections. Namely, the regions of arc discharge plasma in the vicinity of cathode and anode surfaces in the two different configuration of electrodes assembly (copper as a cathode, nickel as an anode and vice versa) were investigated.
