FIELD: technological processes.
SUBSTANCE: invention relates to the field of the powder metallurgy and may be used to produce high-temperature sealing composite coating by method of gas-thermal sputtering in production of gas-turbine engines to provide for stability of clearances in coupled elements of turbine flow path. High-temperature composite material for sealing coating includes components with the following ratio of components, wt %: hexagonal boron nitride 5-15, alumogel 3-6, stabilised dioxide of zirconium of system ZrO2-7-8%Y2O3 - the rest to 100%. At the same time content of the main fraction in the material with particles of 20-100 micrometre of round shape makes at least 70% of the common mass of material.
EFFECT: invention makes it possible to improve quality of produced coating and to simplify method of its application.
