C/C composite material anti-oxidation ablation coating prepared by utilizing polymer conversion ceramic as well as preparation method and application of C/C composite material anti-oxidation ablation coating
The invention discloses a C/C composite material anti-oxidation ablation coating prepared by utilizing polymer conversion ceramic as well as a preparation method and application of the C/C composite material anti-oxidation ablation coating, and relates to the technical field of surface coatings. The method comprises the following steps: preparing polymer converted ceramic powder; the preparation method comprises the following steps: uniformly mixing SiC powder in a phenolic resin ethanol solution to obtain slurry A; uniformly mixing SiC powder and polymer converted ceramic powder in a phenolic resin ethanol solution to obtain slurry B; sequentially coating the surface of the C/C composite material with the slurry A and the slurry B; and carrying out heat treatment on the C/C composite material with the pre-coating layer in an inert atmosphere to obtain the anti-oxidation ablation coating layer on the surface of the C/C composite material. The silicon-rich ceramic coating is prepared by introducing polymer converted superhigh-temperature ceramic into the surface of a C/C composite material by combining slurry coating with a high-temperature gas-phase siliconizing method. The preparation process is low in cost, simple, high in quality reliability and strong in designability.
