| 摘 要： | 采用先驱体转化法(PIP方法)制备C/SiC陶瓷基复合材料,通过调整多孔预制件的体积密度制备出不同组分比的C/SiC复合材料。结果显示,C/SiC复合材料的热膨胀系数随着复合材料中SiC含量的增加而增加,其与CVDSiC涂层之间的热匹配也相应增加,通过CVI方法制备梯度过渡层,在C/SiC复合材料表面制备出致密度较高的CVDSiC涂层。

| Abstract: | C/SiC composites was prepared by ways of polymer infiltration pyrolysis(PIP). C/SiC with different ratio of component was prepared.The result shows that the coefficient of thermal expanding(CET) of C/SiC composites was improved with the increasing of SiC content in composites.The matching between C/SiC composites and CVD SiC was improved simultaneously.Through preparing the gradual layer by ways of chemical vapor infiltration(CVI),CVD SiC with density near 100% can be prepared. |
