TiB2-based composite ceramic with high bending strength and preparation method thereof
The invention belongs to the field of non-oxide structural ceramics, and particularly relates to a high-bending-strength TiB2-based composite ceramic and a preparation method thereof.The high-bending-strength TiB2-based composite ceramic is prepared from TiN powder, B4C powder, Si powder, Al powder, B powder, BN powder, TiB2 powder, AlN powder and SiC powder as raw materials through the steps that powder proportioning is carried out, and the TiB2-based composite ceramic is prepared; the raw material powder is mixed, subjected to rotary evaporation, dried and sieved, and then densified by using a spark plasma sintering method to obtain the required TiB2-based composite ceramic. Through raw material formula optimization, spark plasma sintering process control and subsequent heat treatment-water quenching process, the bending strength of the TiB2 ceramic is remarkably improved, and meanwhile other excellent performance is guaranteed.
本发明属于非氧化物结构陶瓷领域，具体涉及一种高弯曲强度的TiB2基复相陶瓷及其制备方法，以TiN粉体、B4C粉体、Si粉体、Al粉体、B粉体、BN粉体、TiB2粉体、AlN粉体和SiC粉体为原料，进行粉体的配比，将原料粉体混合、旋蒸、干燥、过筛后利用放电等离子烧结的方法实现其致密化，得到所需的TiB2基复相陶瓷。本发明通过原料配方优化、放电等离子烧结工艺控制和后续热处理‑水淬工艺，显著提高TiB2陶瓷的弯曲强度，同时保证其他优良性能。
