The basis for determining the density of electrons in plasma is the study of the broadening of spectral lines, which is caused by the linear Shtark- effect. This article demonstrates the applicability of the classical theory of scattering, with the help of which, analyzing the spectral characteristics of spark plasma discharges in the electrochemical system of magnesium-electrolyte, determined that during the synthesis of oxide-ceramic coatings on a magnesium basis in discharge channels for electron density (3.2…3.4)⋅10²² m⁻³ and their temperatures (1…1.1)⋅10⁴ K equilibrium, not degenerate, quasi-ideal plasma is formed with an ionicity (0.02…0.10). This temperature makes conditions for dissociation and ionization of electrolyte components and also ensures high chemical reactivity. At the same time, the speed of the reaction is much higher compared to classical electrochemical methods. The performed calculations provide the possibility of further correct thermodynamic calculation of the concentrations of the reaction products of the synthesis of oxide ceramic coatings in the electrolytic plasma of the magnesium alloy–electrolyte system.
