Thermal environment barrier coating, preparation method thereof and high-temperature-resistant component
In order to solve the problem that an existing thermal environment barrier coating is insufficient in water and oxygen corrosion resistance, the thermal environment barrier coating comprises a compact layer and a high strain tolerance layer, the compact layer comprises rare earth silicate, and the high strain tolerance layer comprises high-entropy ceramic. Meanwhile, the invention further discloses a high-temperature-resistant component comprising the thermal environment barrier coating and a preparation method of the thermal environment barrier coating. According to the thermal environment barrier coating provided by the invention, the high-density rare earth silicate and the high-entropy ceramic with high strain tolerance are compounded to form the thermal environment barrier coating, so that the problems that the thermal environment barrier coating is easy to generate crack channels, water-oxygen corrosion failure is caused by direct contact with water and oxygen and the like can be effectively reduced; due to introduction of the low-heat-conductivity high-entropy ceramic, the overall water-oxygen-corrosion-resistant effect is improved, the overall heat insulation effect can be further improved, and then the use efficiency of the engine is improved.
