Abstract: Ceramic matrix composites (CMCs) possess excellent properties such as high strength and high-temperature resistance, making them highly promising for applications in the nuclear industry, automotive machinery, aerospace, and other fields. However, the engineering application of CMCs often requires joining with metals, which has spurred extensive research on bonding technologies between CMCs and metallic materials. Among various joining techniques, brazing is considered the optimal method due to its process simplicity and high joint strength. This paper summarizes the current research status and challenges in brazing CMCs to metals, and discusses recent advances from the perspectives of improving the wettability of CMCs surfaces, controlling the formation of brittle interfacial reaction products, and residual stress mitigation methods. Finally, the relevant research achievements are summarized, and prospects for future development trends in brazing technology for CMCs-metal joints are provided.
