Controllable network ceramic/metal composite material preparation process
The invention discloses a controllable network ceramic/metal composite material preparation process, and belongs to the technical field of special materials. The problems that only one material can be formed in conventional 3D printing manufacturing, and formed parts are single in function and limited in performance are solved. According to a composite material, oxide ceramic powder and metal serve as raw materials, a three-dimensional network ceramic green body is formed through the photocuring 3D printing technology, a compact ceramic framework is prepared after high-temperature degreasing sintering, then the compact ceramic framework and the metal are put into a graphite crucible together and put into vacuum pressure permeation equipment to be formed, and finally argon is injected for cooling. According to the controllable network ceramic/metal composite material preparation process, dense combination of the ceramic/metal composite material on the three-dimensional scale can be achieved, the overall appearance, the crystal lattice shape and the pore size of the ceramic framework are optimally designed, the material can have good mechanical performance under different application backgrounds, and function designability is achieved.
本发明公开了一种可控网络陶瓷/金属复合材料制备工艺，属于特种材料技术领域，解决了常规3D打印制造只能成形一种材料且成形部件功能单一、性能有限的问题。本发明复合材料以氧化物陶瓷粉体和金属为原料，利用光固化3D打印技术成型三维网络陶瓷坯体，再经高温脱脂烧结后制得致密陶瓷骨架，随后与金属一同装进石墨坩埚放入真空压力渗透设备中进行成型，最后冲入氩气冷却。本发明能够实现陶瓷/金属复合材料在三维尺度上的致密结合，通过对陶瓷骨架的整体外观、晶格形状与孔隙大小进行优化设计，实现在不同应用背景下该材料都能够有良好的力学性能，具有功能可设计性。
