High-temperature stable phase carbide ceramic reinforced silicon carbide coating and preparation method thereof
The invention relates to the technical field of silicon carbide coatings, in particular to a high-temperature stable-phase carbide ceramic reinforced silicon carbide coating and a preparation method thereof.The high-temperature stable-phase carbide ceramic reinforced silicon carbide coating comprises paste formed by mixing stable-phase carbide ceramic particles and silicon carbide powder, and the stable-phase carbide ceramic particles are evenly distributed in the paste; the coating has a certain volume ratio, so that the coating has excellent stability and durability in a high-temperature environment; the particle size of the particles ranges from 1 micrometer to 50 micrometers, even distribution of the particles in paste can be guaranteed through the proper particle size, and the comprehensive performance of the coating is not affected. The particle size of the silicon carbide powder ranges from 0.1 micrometer to 10 micrometers, and due to the proper particle size, the silicon carbide powder and the stable-phase carbide ceramic particles can be fully mixed. According to the invention, the application range of the coating is widened, and the protection performance of the coating is more excellent.
本发明涉及碳化硅涂层技术领域，具体涉及一种高温稳定相碳化物陶瓷增强的碳化硅涂层及其制备方法，包括稳定相碳化物陶瓷颗粒和碳化硅粉末混合而成的糊状物，其中，所述稳定相碳化物陶瓷颗粒均匀地分布在糊状物中，并具有一定的体积比，使得涂层在高温环境下具有优良的稳定性和耐久性；所述颗粒的粒径在1‑50微米之间，适当的粒径可以保证颗粒在糊状物中的均匀分布，且不影响涂层的综合性能；所述碳化硅粉末的粒径在0.1‑10微米之间，适当的粒径可以使碳化硅粉末与稳定相碳化物陶瓷颗粒充分混合。本发明，提高了涂层的应用范围，涂层的保护性能更加优越。
