A kind of boron carbide-based composite ceramic material and preparation method thereof |
| abstract |
The invention relates to a boron carbide-based composite ceramic material and a preparation method thereof. The composite ceramic material is prepared by mixing boron carbide powder, titanium carbide powder and boron powder uniformly and then sintering under high temperature pressure. The phase composition is boron carbide and titanium boride, and the grain size is 0.8-1.5 μm; the molar ratio of titanium carbide powder and boron powder in the raw material powder is 1:6, and the boron carbide powder accounts for 10-80% of the mass of the raw material powder. . The present invention adopts in-situ reaction synthesis combined with hot pressing sintering densification technology to prepare boron carbide-titanium boride composite ceramic materials with boron carbide content as high as 50-90 wt%, and solves the problem of low boron carbide content in existing in-situ composite boron carbide ceramics. The boron carbide-based composite material also has the characteristics of small grain size, excellent structure, high density, and excellent comprehensive performance. It is important in the fields of wear-resistant ceramic parts and impact-resistant protective materials. application value. |
