Fine-grain boron-rich boron carbide-based composite ceramic material and preparation method thereof
The invention relates to a fine-grain boron-rich boron carbide-based ceramic composite material and a preparation method thereof, the main phases are boron-rich boron carbide and titanium boride, thetitanium boride is dispersed in the boron-rich boron carbide, the boron-rich boron carbide and titanium boride phases are uniformly distributed, and no crack exists between crystal grains. The fine-grain boron-rich boron carbide-based composite ceramic material is prepared from 39.5%-44.3% of titanium carbide powder and 55.7%-60.5% of boron powder in percentage by mass through spark plasma sintering of mixed powder of the titanium carbide powder and the boron powder. The boron-rich boron carbide-titanium boride ceramic composite material provided by the invention has uniform grain size and phase distribution, and the boron carbide-carbon ratio is large and convenient to regulate and control, the material has high density and excellent performance.
本发明涉及一种细晶粒富硼碳化硼基陶瓷复合材料及其制备方法，其主要物相是富硼碳化硼和硼化钛，硼化钛分散在富硼碳化硼中，富硼碳化硼和硼化钛物相分布均匀，晶粒之间无裂纹。所述的细晶粒富硼碳化硼基复合陶瓷材料由碳化钛粉体和硼粉混合粉体，经过放电等离子烧结而成，其中按质量百分比计碳化钛粉体39.5％‑44.3％，硼粉55.7％‑60.5％。本发明提供的富硼碳化硼‑硼化钛陶瓷复合材料具有均匀的晶粒尺寸和物相分布，碳化硼硼碳比大且方便调控；材料具有高的致密度和优异的性能。
