Single-crystal high-temperature alloy-carbon fiber reinforced ceramic matrix composite connecting piece and preparation method thereof
The invention belongs to the technical field of ceramic-based composite materials, and particularly relates to a single-crystal high-temperature alloy-carbon fiber reinforced ceramic-based composite material connecting piece and a preparation method thereof.The preparation method comprises the following steps that S1, a carbon fiber reinforced ceramic-based composite material structure is designed and prepared; s2, carrying out metallization treatment on the surface of the carbon fiber reinforced ceramic matrix composite material prepared in S1; s3, preparing an oxide ceramic mold shell; and S2, connecting the carbon fiber reinforced ceramic-based composite material subjected to surface metallization treatment with a single-crystal high-temperature alloy in a vacuum casting manner by utilizing the ceramic mold shell, after pouring is finished, carrying out heat preservation, cooling and vacuum removal treatment, and removing the ceramic mold shell, so as to obtain the single-crystal high-temperature alloy-carbon fiber reinforced ceramic-based composite material connecting piece. The problem that in the prior art, when the ceramic and the high-temperature alloy are connected, huge residual thermal stress is generated due to different physicochemical properties in a connector is solved, and the strength of the connector is improved.
本发明属于陶瓷基复合材料技术领域，具体涉及一种单晶高温合金‑碳纤维增强陶瓷基复合材料连接件及其制备方法，包括以下步骤：S1、碳纤维增强陶瓷基复合材料结构设计及制备；S2、对S1制备的碳纤维增强陶瓷基复合材料的表面进行金属化处理；S3、制备氧化物陶瓷模壳；利用所述陶瓷模壳将经过S2表面金属化处理后的碳纤维增强陶瓷基复合材料与单晶高温合金通过真空铸造的方式进行连接，浇筑结束后经保温、冷却、除真空处理，除去陶瓷模壳，得到所述单晶高温合金‑碳纤维增强陶瓷基复合材料连接件。本发明缓解了现有技术中陶瓷与高温合金进行连接时接头中因物化性质不同产生的巨大残余热应力的问题，提高了接头强度。
