Bulletproof ceramic and preparation method thereof
The invention provides bulletproof ceramic and a preparation method thereof, a composite coating group is fixed on a bullet facing surface of a ceramic matrix, and the composite coating group comprises at least three columnar crystal layers which are sequentially superposed from bottom to top and are prepared by adopting an electron beam physical vapor deposition (EB-PVD) method, and a lubricating layer prepared by adopting a physical vapor deposition (PVD) method is clamped between the upper and lower adjacent columnar crystal layers. According to the design, at least three columnar crystal layers and two lubricating layers are included, that is, at least two sets of columnar crystal layer-lubricating layer-columnar crystal layer sandwich type sliding structures are provided, it can be guaranteed that projectiles deflect multiple times in the penetration process, and therefore the overall penetration resistance of the bulletproof ceramic is guaranteed.
本发明提供了一种防弹陶瓷及其制备方法，在陶瓷基体的迎弹面上固定有复合涂层组，复合涂层组包括由下至上依次叠加的至少三层分别由采用电子束物理气相沉积方法(EB‑PVD)制备而成的柱状晶层，上、下相邻的两层柱状晶层之间夹设有一层采用物理气相沉积方法(PVD)制备而成的润滑层。本发明的设计中，包括了至少三层柱状晶层和两层润滑层，即提供了至少两组“柱状晶层‑润滑层‑柱状晶层”的夹心式滑移结构，可保证弹丸在侵彻时发生多次偏转，从而保证防弹陶瓷整体的抗侵彻能力。
