Alumina (Nextel™ 610) fibre reinforced YAG-ZrO₂ matrix composites were successfully joined by using different brazing alloys, metallic interlayers and a glass-ceramic. All joints were mechanically stable and free of cracks. Three commercial brazing alloys and a new alloy based on Ti/Cu/Al interlayers were selected to join these composites for applications in a non-oxidizing environment. A glass-ceramic based on SiO₂-Al₂O₃-CaO-MgO was developed in case the joined component needs to be oxidation resistant. To evaluate the thermal stability, all joined composites were aged up to 100 h in air at 550 °C for brazing joints or 850 °C and 930 °C for glass-ceramic joints. The mechanical strength was measured using single lap and four point bending tests before and after ageing. Four point bending tests on glass-ceramic joined samples showed an average joint strength of about 70 MPa which is 35% of as-received composites.

氧化铝（Nextel™610）纤维增强的YAG-ZrO ₂基复合材料通过使用不同的钎焊合金，金属中间层和玻璃-陶瓷成功地连接在一起。所有接头均机械稳定且无裂纹。选择了三种商用钎焊合金和一种基于Ti / Cu / Al中间层的新型合金，以将这些复合材料连接起来以用于非氧化环境。基于SiO ₂ -Al ₂ O _3的玻璃陶瓷-CaO-MgO被开发出来，以防连接的组件需要抗氧化。为了评估热稳定性，将所有连接的复合材料在550°C的空气中进行铜焊接头老化，或在850°C和930°C的玻璃陶瓷接头中在空气中老化100小时。在老化之前和之后，使用单圈和四点弯曲测试来测量机械强度。在玻璃-陶瓷接合的样品上进行的四点弯曲测试显示，平均接合强度约为70 MPa，是原样复合材料的35％。
