The Zr-Cu filler metal is mainly used for the joining of SiC ceramic as a nuclear fuel cladding material. The physical and chemical properties of the alloy, the interfacial reaction between the Zr-Cu filler metal and SiC ceramic, the residual stress of the SiC joint and the thermal neutron absorption cross section of the filler metal are considered during the design of the Zr-Cu filler metal. 80Zr-20Cu (wt%) is used as the filler metal in these experiments, showing good wettability and brazing properties with SiC ceramic.
Zr-Cu填充金属主要用于作为核燃料包壳材料的SiC陶瓷的连接。在Zr-Cu填充金属的设计过程中，考虑了合金的物理和化学性质、Zr-Cu填充金属与SiC陶瓷之间的界面反应、SiC接头的残余应力以及填充金属的热中子吸收截面。在这些实验中，使用80Zr-20Cu（重量%）作为填充金属，其对SiC陶瓷表现出良好的润湿性和钎焊性能。
