TiC-TiB2 double-phase toughened aluminum-magnesium-boron composite ceramic and preparation method thereof
The invention provides TiC-TiB2 double-phase toughened aluminum-magnesium-boron composite ceramic and a preparation method thereof, and belongs to the technical field of composite materials. The method comprises the following steps: mixing a magnesium-containing compound, an aluminum-containing compound, a boron-containing compound and Ti powder in proportion, and carrying out ball milling and electric field activation pressurization reaction to obtain the TiC-TiB2 two-phase toughened aluminum-magnesium-boron composite ceramic. The prepared composite ceramic is composed of three phases of AlMgB14, TiB2 and TiC, no MgAl2O4 spinel phase exists, and the toughness and wear resistance of the composite ceramic are remarkably improved.
本发明提供了一种TiC‑TiB2双相增韧铝镁硼复合陶瓷及其制备方法，属于复合材料技术领域。本发明将含镁化合物、含铝化合物、含硼化合物和Ti粉按照比例混合后，经球磨和电场激活加压反应，制备得到TiC‑TiB2两相增韧的铝镁硼复合陶瓷。制备所得的复合陶瓷由AlMgB14、TiB2和TiC三相组成，不存在MgAl2O4尖晶石相，显著提高了复合陶瓷的韧性和耐磨性。
