异种陶瓷材料微波连接的研究

Study on the Microwave Joining for Dissimilar CeramicMaterials

采用微波加热方法与常规加热方法对ＺｒＯ２增韧Ａｌ２Ｏ３（ＺＴＡ）、Ｙ２Ｏ３稳定的四方相ＺｒＯ２（Ｙ—ＴＺＰ）进行连接试验。结果表明，利用微波加热可以顺利实现异种陶瓷之间的连接。与常规方法相比，微波加热可以快速完成连接过程，被连接陶瓷材料之间界面结合状态良好，连接强度更高。

Zirconia toughened alumina (80 wt% Al 2O 3+20 wt% ZrO 2) and tetragonal zirconia polycrystallines (doped with 2.7 mol% Y 2O 3) were joined by using microwave and conventional heating. The experimental results show that joining of ceramic materials with different properties by microwave could be carried out successfully. Comparing with the conventional method, microwave joining for dissimilar ceramic materials could be completed at a faster rate or a lower temperature with finer grain size, better interfacial bonding and higher joint strength.
