| titleOfInvention | In-situ reaction for preparing MB2Method for preparing (E) -MC-BN ultrahigh temperature ceramic matrix composite material |
| abstract | The invention belongs to the field of ultra-high temperature ceramics, and particularly relates to an in-situ reaction preparation methodSpare MB 2 -MC-BN ultra high temperature ceramic matrix composite material. The raw materials consist of MN powder (M ═ Ti, Zr, Hf or Ta) and B 4 C powder is mixed and then is subjected to in-situ reaction hot-pressing sintering in a hot-pressing furnace or reaction sintering in a discharge plasma sintering furnace. Under the protective atmosphere, the heating rate is 10-100 ℃/min, the sintering temperature is 1900-2100 ℃, the sintering time is 10 min-2 h, the sintering pressure is 20 MPa-40 MPa, and finally the MB is obtained 2 -MC-BN composite materials (M ═ Ti, Zr, Hf or Ta) which are candidates for high temperature resistant structural elements such as the nozzle throat of solid rocket engines or the nose cone, wing leading edge of very high speed aircraft. |
