摘要

陶瓷材料因具有高强度、低密度、耐高温及耐腐蚀等优异性能，在航空航天领域具有广阔的应用前景。针对传统成形工艺在制备复杂结构陶瓷零件的局限性，本文研究了钛酸钡（BT）/羟基磷灰石（HA）复合压电陶瓷的还原光聚合（Vat Photopolymerization，VPP）增材制造工艺。通过优化陶瓷粉体配比、光敏树脂组成及添加剂含量，成功制备了体积分数为40%、兼具高固含量与高分散性的BT/HA复合压电陶瓷浆料，其中BT与HA的体积比为4∶1。基于比尔-朗伯（Beer-Lambert）定律，预测并分析了该浆料的最优打印工艺参数，并制备出成形质量良好的BT/HA复合陶瓷坯体。结果表明，所成形坯体的最小结构特征尺寸可达100 μm，悬臂梁结构的最大无支撑跨距为10 mm。

Abstract

Ceramic materials exhibit broad application prospects in the aerospace field due to their excellent properties such as high strength

low density

high temperature resistance

and corrosion resistance. To address the limitations of traditional forming methods in fabricating ceramic parts with complex structures

this paper investigates the Vat Photopolymerization (VPP) additive manufacturing process of barium titanate (BT)/hydroxyapatite (HA) composite piezoelectric ceramics. By optimizing the ceramic powder ratio

photosensitive resin composition

and additive content

a BT/HA composite piezoelectric ceramic slurry with a solid loading of 40 vol%

characterized by high solid content and high dispersibility

was successfully prepared

wherein the volume ratio of BT to HA is 4:1. Based on the Beer-Lambert law

the optimal printing process parameters of the slurry were predicted and analyzed

and BT/HA composite ceramic green bodies with good formability were fabricated. The results show that the minimum structural feature size of the obtained green bodies reaches 100 μm

and the maximum unsupported span of the cantilever beam structure is 10 mm.
