Preparation process of 3D printing silicon carbide ceramic-based composite material
The invention discloses a 3D printing silicon carbide ceramic-based composite material preparation process capable of realizing simultaneous printing, powder cleaning and workpiece taking at three stations in a 3D printing process. The preparation process of the 3D printing silicon carbide ceramic-based composite material comprises the following steps: S1, selecting SiC powder and an adhesive; s2, preparing composite powder; s3, a SiC ceramic initial blank is printed; and S4, performing densification treatment on the SiC ceramic initial blank by adopting a vacuum degreasing and PIP (Polyisoprene-Polyisoprene-Polyisoprene) impregnation cracking process. And a 3D printing laser sintering system is adopted in the step S3. By adopting the preparation process of the 3D printing silicon carbide ceramic-based composite material, rapid preparation of the silicon carbide ceramic-based composite material can be realized; the preparation efficiency of the silicon carbide ceramic-based composite material is improved, and the production cost is reduced.
本发明公开了一种能够在3D打印过程中实现打印、清粉、取件三工位同时进行的3D打印碳化硅陶瓷基复合材料制备工艺。该3D打印碳化硅陶瓷基复合材料制备工艺包括步骤S1、选取SiC粉体以及粘接剂；S2、制备复合粉体；S3、打印SiC陶瓷初坯；S4、采用真空脱脂和PIP浸渍裂解工艺对SiC陶瓷初坯进行致密化处理。并且在步骤S3中采用3D打印激光烧结系统。采用该3D打印碳化硅陶瓷基复合材料制备工艺能够实现碳化硅陶瓷基复合材料的快速制备；制备碳化硅陶瓷基复合材料制备效率，降低生产成本。
