但是,在1500℃以上,SiC氧化产物SiO2的抗氧化保护作用被严重削弱。为提高CMC–SiC复合材料的耐高温、抗烧蚀和抗氧化性能,以满足其在高超音速飞行器及航空发动机上的应用,需对其进行基体改性。
目前对基体的改性尚缺乏成功将Hf、Zr、Ta等抗烧蚀组元引入碳化硅陶瓷基以提高碳化硅陶瓷基复合材料的耐高温能力的方法和手段。
发明内容
本发明公开了一种超高温碳化硅陶瓷基复合材料的制备方法,该方法提高了制成的碳化硅陶瓷基复合材料的抗氧化性能和抗烧蚀性能。
一种超高温碳化硅陶瓷基复合材料的制备方法,包括以下步骤:
①将二维平纹碳化硅纤维布裁剪为方形;
②将裁剪好的碳化硅纤维布叠层,并用碳化硅纤维缝合线缝合为一整体,定型得到碳化硅纤维预制体;
③将碳化硅纤维预制体放入化学气相沉积炉中进行化学气相沉积,制备热解碳界面层;
④将含有抗烧蚀组元的陶瓷粉体与前驱体溶液配制成浸渍浆料,其中陶瓷粉体含量为2~20wt%,粘度为50~400mPa·s;
⑤将③中的预制件在④中的浸渍液中真空高压浸渍;
⑥将⑤中的预制件取出沥干后高压固化;
⑦将⑥高压固化后的预制件高温裂解,在氮气气氛中以5~10℃/min的升温速率升至1000~1200℃,保温60~120min,自然降温至室温;
⑧反复进行⑤~⑦步,直至预制体的重量变化小于目标值或设定值。

在本申请的一个或多个具体地实施方式中,所述抗烧蚀组元为Si3N4、SiC、ZrB2、ZrC、HfC、HfB2、BN和B4C中的一种或多种。
在本申请的一个或多个具体地实施方式中,所述抗烧蚀组元其颗粒粒径小于100nm。
在本申请的一个或多个具体地实施方式中,所述前驱体溶液为聚碳硅烷溶液。

本发明还提供一种浸渍浆料。
一种超高温碳化硅陶瓷基复合材料,所述超高温碳化硅陶瓷基复合材料为上述的超高温碳化硅陶瓷基复合材料的制备方法制备而成。
发明原理及有益效果:
本申请通过化学气相沉积热解碳界面层,在将浸渍浆料制备时将含有抗烧蚀组元的陶瓷粉体引入前驱体溶液,真空高压浸渍等手段,制成的碳化硅陶瓷基复合材料中ZrB2和ZrC颗粒均匀地弥散在SiC连续相中,形成了ZrB2-ZrC-SiC复相陶瓷基体。由于ZrB2、ZrC颗粒与SiC紧密地结合在一起,可在高温氧化环境中产生协同效应,有利于提高复合材料的抗氧化性能和抗烧蚀性能。而且,在碳化硅陶瓷基复合材料中,SiC相均匀遍布于基体中,形成了连续相,ZrB2和ZrC纳米颗粒均匀弥散在基体中。而且粒径小于100nm的ZrB2和ZrC颗粒有利于显著提高复合材料基体中各相的比表面积和陶瓷活性,并在超高温氧化环境应用时产生强烈的协同效应。
