C/(SiC/BN)n compound interface phase coating, coating fiber and preparation method of coating fiber
The invention discloses a C/(SiC/BN)n compound interface phase coating which comprises a C layer and a periodic superposed layer, wherein the periodic superposed layer refers to alternative periodic superposition of SiC layers and BN layers. The coating fiber comprises a fiber base body and the C/(SiC/BN)n compound interface phase coating applied to the surface of the base body, wherein the fiber base body is selected from one of mullite fiber, carbon fiber, silicon carbide fiber and quartz fiber. The preparation method of the coating fiber comprises the following steps: preparing a fiber base body material, and depositing the C layer on the surface of the fiber base body with a chemical vapor deposition method at first; then alternatively depositing the SiC layers and the BN layers on the surface of the C layer with the chemical vapor deposition method, repeating the alternative depositing process 3-5 times, and obtaining the coating fiber. The coating fiber has the advantages of good physical and chemical compatibility, high temperature resistance, oxidation resistance, good toughening effect and the like.
