Aluminum-containing high-entropy carbonitride ceramic and preparation method thereof
The invention discloses aluminum-containing high-entropy carbonitride ceramic and a preparation method thereof.The aluminum-containing high-entropy carbonitride ceramic is composed of a high-entropy carbonitride ceramic matrix and AlN particles distributed in the high-entropy carbonitride ceramic matrix in a dispersed mode, and the high-entropy carbonitride ceramic matrix contains Al. A high-entropy carbonitride ceramic matrix contains Al and also contains in-situ generated AlN second-phase particles, the Al and the in-situ generated AlN particles respectively utilize solid solution strengthening and second-phase strengthening to improve the mechanical property of the high-entropy ceramic, and meanwhile, the oxidation resistance of the high-entropy ceramic is improved due to the formation of an aluminum-containing oxide in the oxidation process. Therefore, the aluminum-containing high-entropy carbonitride ceramic provided by the invention has good mechanical properties and excellent oxidation resistance.
