Abstract
The application provides a preparation method of a two-phase high-entropy ceramic powder and coating. The preparation method first prepares a micro-sized spherical two-phase high-entropy ceramic powder through a spray granulation method; a high-density, high-fluidity, high-bulk-density high-quality standard spherical two-phase high-entropy ceramic powder is prepared by using a radio frequency induction plasma spheroidization method, and the powder has a face-centered cubic crystal structure and a body-centered cubic crystal structure. A two-phase high-entropy ceramic coating is prepared on the surface of a substrate by using a supersonic plasma spraying technology. The coating prepared by the application has excellent phase stability and oxidation resistance and ablation resistance, and can withstand more than 120 seconds of super-high-temperature heat protection in an electric arc plasma ablation process at 1800 DEG C.
