Rapid densification multiphase matrix of silicon carbide ceramic-based composite material and preparation method of rapid densification multiphase matrix
The invention discloses a rapid densification multiphase matrix of a silicon carbide ceramic-based composite material and a preparation method of the rapid densification multiphase matrix. According to the preparation method, the technical main line of preparing the multi-phase SiC ceramic composite material through cooperation of the precursor impregnation and pyrolysis process and the reaction melting siliconizing process is adopted, the microstructure of the composite material prepared through the mixing process is optimized and improved by regulating the introduction sequence of the reaction activated carbon and the ceramic matrix prepared through the precursor impregnation and pyrolysis process, and the mechanical property of the material is effectively improved. Compared with a ceramic-based composite material prepared by an existing melt siliconizing process, the method has the advantage that the mechanical property is better. Meanwhile, compared with a ceramic precursor impregnation cracking process, the preparation period is greatly shortened.
本发明公开了一种碳化硅陶瓷基复合材料快速致密多相基体及其制备方法。本发明以前驱体浸渍裂解工艺与反应熔融渗硅工艺协同制备多相SiC陶瓷复合材料为技术主线，通过调控反应活性炭与前驱体浸渍裂解工艺制备的陶瓷基体引入顺序优化改善混合工艺制备的复合材料微观结构，有效提升材料力学性能。该方法与现有熔融渗硅工艺制备的陶瓷基复合材料相比，力学性能更优。同时，相较于陶瓷前驱体浸渍裂解工艺，制备周期大幅降低。
