Integrated preparation method of environmental barrier coating SiCf/SiC ceramic-based composite material
The invention relates to an integrated preparation method of an environmental barrier coating SiCf/SiC ceramic-based composite material, which comprises the following steps: attaching at least one layer of ceramic biscuit film containing a rare earth compound to the surface of a partially densified SiCf/SiC porous composite material, and then carrying out curing, cracking and liquid-phase siliconizing to realize densification, thereby obtaining the SiCf/SiC ceramic-based composite material. And the environment barrier coating-SiCf/SiC ceramic matrix composite material is obtained.
本发明涉及一种环境障碍涂层‑SiCf/SiC陶瓷基复合材料的一体化制备方法，包括：将至少一层含稀土化合物的陶瓷素坯薄膜贴附在部分致密化的SiCf/SiC多孔复合材料的表面，再经过固化、裂解和液相渗硅后实现致密化，得到所述环境障碍涂层‑SiCf/SiC陶瓷基复合材料。
