| 摘 要： | 采用三点弯曲及扫描电镜等方法研究了ＳｉＣｗ／Ａｌ２Ｏ３、ＳｉＣｗ／ＺｒＯ３（Ｙ２Ｏ３）及ＳｉＣｗ／Ａｌ２Ｏ３＋ＺｒＯ２（Ｙ２Ｏ３）陶瓷复合材料的抗热震性．结果表现ＳｉＣｗ的加入使Ａｌ２Ｏ３、ＺｒＯ２（Ｙ２Ｏ３）以及Ａｌ２Ｏ３＋ＺｒＯ２（Ｙ２Ｏ３）基体的抗热震性显著提高，Ａｌ２Ｏ３陶瓷基复合材料的抗热震性明显优于ＺｒＯ２（Ｙ２Ｏ３）陶瓷基复复合材料．同时发现在Ａｌ２Ｏ３十ＳｉＣｗ材料基础上再加入少量ＺｒＯ２（２Ｙ）颗粒（１０Ｖｏ１％），也可进一步提高Ａｌ２Ｏ３＋ＳｉＣｗ材料的抗热震性．

| Abstract: | The thermal shock properties of SiCw/Al2O3. SiCw/ZrO2 (Y2O3) andSiCw/Al2O3+ZrO2(Y2O3) ceramic matrix composites have been investigated by means oftheree--point bending and SEM techniques. The results show that the thermal shockproperties of Al2O3, ZrO2 (Y2O3) and Al2O3+ZYO2 (Y2O3) matrices are improvedsignificantly by the addition of SiCw and the property of Al2O3 matrix composites ismuch better than that of ZrO2(Y2O3)matrix ones. The thermal shock properties ofAl2O3+SiCw composites are also further improved by adding a little of ZrO2(2Y) particles (10vo1%) on the basis of Al2O3+SiCw composites. |
