ZrC-SiC ceramic and TC4 alloy were successfully brazed using a self-prepared Ti-15Cu-15Ni filler. The microstructure and mechanical property of the joints obtained at different brazing temperatures were investigated. The results indicated that Ti from the Ti-15Cu-15Ni and the TC4 reacted with the ZrC-SiC to form TiC phase adjacent to the ZrC-SiC ceramic. In the brazing seam, Ti₂(Ni, Cu) intermetallic compounds zone (IMCs Zone), Hypoeutectic Zone and Hypereutectoid Zone formed. The brazing temperature affected the dissolution of TC4 into the braze filler significantly, and then determined the microstructure of the joint. The formation of α-Ti in the brazing seam could decrease the hardness and the brittleness of the brazing seam, which was beneficial to the property of the brazed joint. The joint strength reached a maximum value of 43 MPa when the joint was brazed at 970 °C and cracks propagated in the ZrC-SiC substrate near the brazing seam.

使用自行制备的Ti-15Cu-15Ni填料成功钎焊ZrC-SiC陶瓷和TC4合金。研究了在不同钎焊温度下获得的接头的组织和力学性能。结果表明，Ti-15Cu-15Ni和TC4中的Ti与ZrC-SiC反应形成与ZrC-SiC陶瓷相邻的TiC相。在钎焊层中，Ti ₂形成（Ni，Cu）金属间化合物区（IMCs区），亚共晶区和超共析区。钎焊温度显着影响TC4在钎料中的溶解，然后确定接头的微观结构。在钎焊缝中形成α-Ti会降低钎焊缝的硬度和脆性，有利于钎焊接头的性能。当接头在970°C钎焊时，接头强度达到43 MPa的最大值，并且裂纹在钎焊缝附近的ZrC-SiC基底中扩展。
