| 摘 要： | 采用stöber法制备出单分散氧化硅小球, 并以此为模板, 结合先驱体转化技术成功制备出C/SiC复合材料纳米有序多孔陶瓷接头, 并对该接头制备工艺条件作了优化。对制备出的C/SiC多孔陶瓷接头分别采用先连后浸法(SJM)和直接浸渍法(DSM)进行了连接。结果显示, 两种方法连接的连接件的抗弯强度分别达82.4和20.5 MPa, 表明C/SiC多孔陶瓷接头采用SJM连接较好。

| Abstract: | Mono-dispersed silica spheres were prepared as template by st?ber method. Based on this template, the ordered nanoporous ceramic joints on the C/SiC composites were successfully fabricated for the first time by preceramic polymer techniques and the condition was optimized. Two different joining methods, directly soaking (DSM) and soaking after the first joining (SJM), were used for joining the ordered nanoporous ceramic joints of the C/SiC composites. The result shows that the bending strength of the joints by DSM and SJM is about 20.5 and 82.4 MPa, respectively, suggesting SJM more suitable for joining C/SiC composites. |
