The invention discloses a reinforced porous ceramic joint, and belongs to the field of ceramic joints, the reinforced porous ceramic joint comprises ZTA ceramic with the oxidation error mass fraction of 20%, Ag-18Cu powder brazing filler metal and aluminum borate whiskers; the aluminum borate crystal whiskers are added into the Ag-18Cu powder brazing filler metal, the linear expansion coefficient of the brazing filler metal can be reduced, and meanwhile due to the performance of the crystal whiskers serving as anisotropic materials, the strength of a brazed joint can be improved after the aluminum borate crystal whiskers are added.
本发明公开了一种强化多孔的陶瓷接头，属于陶瓷接头领域，本发明包括含有含氧化错质量分数为20%的ZTA陶瓷、Ag‑18Cu粉末钎料和硼酸铝晶须；本发明通过Ag‑18Cu粉末钎料加入硼酸铝晶须，有利于减少钎料线膨胀系数，同时由于作为各项异性材料的晶须的自身性能，加入后可以提高钎焊接头的强度。
