摘要: 采用无压烧结工艺碳化硼陶瓷制造防弹插板，在高温条件下采用95式5.8 mm钢芯弹对其进行了打靶试验，结果表明防弹插板能够防住8发5.8 mm钢芯弹的连续打击，具有良好的抗多发弹打击性能。采用X射线无损探伤、扫描电镜、能谱面扫描对弹击区陶瓷的微观组织进行分析，碳化硼陶瓷具有由B4C、SiC两相构成的空间网络结构，陶瓷存在宏观和微观裂纹的扩展偏转现象，微观裂纹以穿晶断裂为主要扩展模式并在B4C-SiC相界面及碳化硅内发生偏转，提高了陶瓷能量耗散性能。
Abstract: Pressureless sintered boron carbide bulletproof insert plates were tested by 95 type 5.8 mm steel core bullets under high temperature conditions. The results show that the bulletproof insert plates can withstand 8 rounds hit of 5.8 mm steel core bullets, exhibiting good multi-hit ballistic performance. The microstructure of the ceramic in the bullet impact area was analyzed using X-ray flaw detector, scanning electron microscope and EDS mapping. The boron carbide ceramic has a spatial network structure composed of B4C and SiC phases. Macroscopic and microscopic crack deflection were observed in ceramics. Microscopic crack is mainly propagated by transcrystalline fracture and deflected at the B4C/SiC phase interface and in silicon carbide area, which improves the energy dissipation performance of ceramics.
