Preparation method of high-performance ZrB2-SiC ultrahigh-temperature ceramic for aerospace
The invention discloses a preparation method of high-performance ZrB2-SiC ultra-high-temperature ceramic for aerospace, which comprises the following steps: firstly, coating the surface of SiC powder with atomic state W by using hexacarbonyl W and a chemical vapor deposition method, and then mixing the atomic state W coated SiC powder and ZrB2 powder by using an electromagnetic stirring method to obtain ultra-high-temperature ceramic powder, and finally, the compact preparation of the ZrB2-SiC ultra-high-temperature ceramic is realized by adopting an SPS technology. The ZrB2-SiC ultrahigh-temperature ceramic prepared by the method has the structural characteristics of high compactness and fine grains, has high fracture toughness and excellent high-temperature oxidation resistance, and has a wide application prospect in the field of aerospace.
