Hafnium silicate/ytterbium silicate superhigh-temperature environmental barrier coating and preparation method thereof
The invention relates to the technical field of high-temperature protective coatings, in particular to a hafnium silicate/ytterbium silicate ultrahigh-temperature environmental barrier coating and a preparation method thereof.A hafnium silicate bonding layer, an ytterbium disilicate transition layer and an ytterbium monosilicate working top layer are sequentially deposited on the surface of a ceramic-based composite material matrix; the hafnium silicate/ytterbium silicate superhigh-temperature environmental barrier coating can enable a ceramic-based composite material hot end component to serve at a higher use temperature (higher than 1400 DEG C), and the superhigh-temperature environmental barrier coating system can be applied to the field of high-performance gas turbine engines, especially aero-engines. The ultrahigh-temperature environment barrier coating has high bonding strength, excellent coating interface stability and good water-oxygen and molten salt corrosion resistance, the heat efficiency of an engine is improved, the service life of the engine is prolonged, and the development trend of advanced aero-engines in the future to high thrust, high thrust-weight ratio, high heat efficiency and low emission is met.
