Preparation method for improving photocuring forming performance and high-temperature performance of carbide composite ceramic material
The invention belongs to the technical field of carbide and carbide composite ceramic additive manufacturing, and particularly relates to a preparation method for improving the photocuring forming performance and the high-temperature performance of a carbide composite ceramic material. The refractory rare metal is deposited on the surface layer of the carbide powder, the curing performance of the carbide ceramic material is improved, and then the carbide composite ceramic with enhanced high-temperature performance is obtained through light curing additive manufacturing and densification heat treatment. Compared with the photocuring performance and high temperature resistance of ceramic slurry prepared by directly adopting a carbide material, the prepared refractory rare metal modified layer is uniformly deposited on the surface layer of the carbide, the curing depth of the ceramic slurry can be effectively improved, and the high-temperature pyrolysis degreasing and in-situ reaction sintering are matched, so that the high-temperature resistance of the ceramic slurry is improved. The high-temperature reinforced phase is uniformly distributed in the ceramic matrix, so that the compactness and the high-temperature resistance of the carbide composite ceramic are improved.
本发明属于碳化物及其复合陶瓷增材制造技术领域，具体涉及一种提高碳化物复合陶瓷材料光固化成形性能和高温性能的制备方法。本发明将难熔稀有金属沉积在碳化物粉体表层，提高碳化物陶瓷材料的固化性能，再经光固化增材和致密化热处理，获得高温性能增强的碳化物复合陶瓷。与直接采用碳化物材料制备的陶瓷浆料的光固化性能及耐高温性能进行对比，本发明制备的难熔稀有金属改性层均匀沉积在碳化物表层，能够有效提高陶瓷浆料的固化深度，配合高温热解脱脂及原位反应烧结，高温增强相均匀分布在陶瓷基体内部，提高碳化物复合陶瓷的致密度及耐高温性能。
