Metal reinforced silicon carbide cladding tube and manufacturing method thereof
The invention discloses a metal reinforced silicon carbide cladding tube and a manufacturing method thereof. The manufacturing method of the metal reinforced silicon carbide cladding tube comprises the following steps: S1, respectively obtaining a metal inner tube and a SiCf/SiC composite tube; s2, the metal inner pipe is inserted into the SiCf/SiC composite pipe; and S3, the metal inner pipe is subjected to plastic deformation treatment, so that the metal inner pipe is tightly attached to the SiCf/SiC composite pipe, and the metal reinforced silicon carbide cladding pipe is formed. The high-compactness metal inner pipe is arranged in the SiCf/SiC composite pipe, the cladding pipe of a double-layer structure is obtained, the air tightness of the cladding pipe is improved, and the fission gas release risk is reduced; the metal inner pipe and the SiCf/SiC composite pipe are tightly attached in a plastic deformation mode, generation of by-products on the metal inner pipe and the SiC interface is effectively reduced, and the cladding reliability is improved.
本发明公开了一种金属增强碳化硅包壳管及其制造方法，金属增强碳化硅包壳管的制造方法包括以下步骤：S1、分别获得金属内管和SiCf/SiC复合管；S2、将所述金属内管插入所述SiCf/SiC复合管内；S3、对所述金属内管进行塑性变形处理，使所述金属内管与所述SiCf/SiC复合管紧密贴合，形成金属增强碳化硅包壳管。本发明通过在SiCf/SiC复合管内设置致密性高的金属内管，获得双层结构的包壳管，提高包壳管的气密性，降低裂变气体释放风险；以塑性变形方式实现金属内管和SiCf/SiC复合管的紧密贴合，有效减少金属内管与SiC界面副产物的产生，提高包壳可靠性。
