he paper describes the materials used to obtain sealing coatings that can be operated at a temperature of about 1100 C. The features of the flame spraying process are described. A study was made of the phase composition and structure of the resulting coatings. The distribution of residual stresses over the coating thickness and residual stresses in the first layer are obtained. Data were obtained on the effect of ligatures containing yttrium on the thermophysical characteristics of coatings. Based on the implementation of the plan of a numerical experiment to determine the frequency of natural vibrations of samples coated with a run-in coating when varying the modulus of elasticity of the coating and temperature, as well as solving the inverse problem associated with establishing the dependence of the modulus of dynamic elasticity on the frequency of natural vibrations of a sample with a coating, a calculation-experimental methodology for determining the dynamic modulus of elasticity of running-in sealing coatings of turbine engines.
