Direct-writing forming based preparation method for multielement ceramic functional gradient material
The invention discloses a direct-writing forming based preparation method for a multielement ceramic functional gradient material, and belongs to the technical field of additive manufacturing. The technical problem to be solved in the invention is that there is no proper direct-writing forming technology for preparing the multielement ceramic functional gradient material. The preparation method comprises the following steps: separately injecting different ceramic slurry into multiple layers of coaxial feed cylinders; independently controlling each layer of the feed cylinders to perform extrusion in a direct-writing forming process, thereby obtaining multielement ceramic functional gradient material blanks; and freeze-drying, and vacuum-sintering to obtain the multielement ceramic functional gradient material. A compounding way of multielement materials can be adjusted, so that control on functional gradient of the ceramic materials is realized, and a design range of the ceramic functional gradient material is increased.
本发明公开了基于直写成型的多元陶瓷功能梯度材料的制备方法，属于增材制造技术领域领域。本发明解决的技术问题是目前还没有合适的直写成型技术用于制备多元陶瓷功能梯度材料。本发明制备方法是将不同陶瓷浆料分别注入多层同轴料筒中，通过在直写成型过程中独立控制每层料筒挤出，从而获得多元陶瓷功能梯度材料素坯，然后经冷冻干燥、真空烧结，获得多元陶瓷功能梯度材料。本发明可调整多元材料的复合方式，实现陶瓷材料功能梯度的可控，扩大了陶瓷功能梯度材料的设计范围。
