Paper Title:
Microstructure and Mechanical Property of the ZrB2-Based Ultra-High-Temperature Ceramic Composites Brazed Joint
  Abstract

ZrB2-SiC ceramic composites was brazed by using Ti-Zr-Ni-Cu active filler in a vacuum furnace. The microstructure and interfacial phenomena of the joints were analyzed by means of SEM, EDS and XRD. The joining effect was evaluated by shear strength. The results showed that the reaction products of the ZrB2-SiC ceramic composites joint brazed with Ti-Zr-Ni-Cu active filler were TiC, ZrC, Ti5Si3, Zr2Si, Zr(s,s) and (Ti, Zr)2 (Ni, Cu). The maximum shear strength of the ZrB2-based ultra-high-temperature ceramic composites brazed joints is 143.5 Subscript textMPa at brazing temperature T=920°C and holding time t=10min.
