TiC-TiB2细晶陶瓷装甲抗钨合金长杆动能弹侵彻试验
摘要
通过超重力下燃烧合成工艺制备出不同厚度的TiC-TiB2细晶复合陶瓷
并对TiC-TiB2陶瓷靶板进行径向与纵向约束。经钨合金长杆动能弹进行弹道测试表明
当陶瓷靶板厚度小于12mm时
长杆弹侵彻过程仅包括初始撞击阶段和稳态侵彻阶段
使得陶瓷抗动能弹侵彻能力较差;当陶瓷靶板厚度大于12mm时
弹丸的侵彻过程主要受稳态侵彻与非稳态侵彻（弹丸减速与磨损加速）控制
使得长杆动能弹质量与动能急剧衰减
进而提升陶瓷靶板的抗侵彻能力。
Abstract
Fine-grained TiC-TiB2 composite ceramics with varied thickness was prepared successfully by combustion synthesis under high gravity
and the TiC-TiB2 ceramic ballistic targets were confined by shrink-fit steel in radial and longitudinal direction. Ballistic testing of long-rod kinetic-energy tungsten alloy penetrator shows that
with thickness of ceramic tile lower than 12 mm
the penetration process of ceramic tile are mainly controlled by the combination of the initial-shocking and steady-state penetration
resulting in poor ballistic performance. With the thickness more than 12 mm
the penetration process of the ceramic tile is controlled by the combination of steady-state and un-steady state（projectile deceleration and erosion acceleration） penetration
leading to the sharp attenuation of mass and kinetic energy of the penetrator
greatly improving the ballistic performance of the ceramic tile.
