The purpose of this work is thermodynamic modeling of obtaining alitated coatings doped with chromium under the conditions of self-propagating high-temperature synthesis. Investigation of the mechanism of forming a protective coating on structural materials was carried out using the method of thermodynamic analysis of possible chemical reactions between the components of the system. For this purpose, the interaction of the gas saturated medium formed in the SHS process and the material was calculated. For thermodynamic analysis of the SHS process of forming alitated coatings, we use the universal program of calculation of multicomponent heterogeneous systems TERRA, created on the basis of the ASTRA-4 program under the environment WINDOWS and worked out for high-temperature processes. Unlike traditional methods in chemical thermodynamics, methods of calculating the equilibrium parameters using Gibbs energy, equilibrium constants, and Goldberg and Vage law, the universal program of TERRA thermodynamic calculations is based on the maximum entropy principle for isolated thermodynamics. It is characterized by a maximum of entropy in terms of thermodynamic degrees of freedom, which include concentrations of system components, temperature, pressure.
