Preparation method of silicon carbide coating on surface of silicon carbide fiber
The invention discloses a preparation method of a silicon carbide coating on a silicon carbide fiber surface, which adopts a layer-by-layer self-assembly mode to form a SiC coating on a SiCf surface, realizes the preparation of the coating of a composite material through a simple preparation process, has low requirements on equipment, can consume short fibers and waste filaments generated in the SiC fiber production process, meets the requirements of mass production, and is suitable for industrial production. And the fiber and the coating are both made of SiC materials, so that the phenomena of coating cracking, separation and peeling caused by thermal expansion difference cannot occur under the high-temperature working condition.
本发明公开一种碳化硅纤维表面的碳化硅涂层的制备方法，采用层层自组装方式形成SiCf表面的SiC涂层，通过简便的制备过程实现复合材料的涂层的制备，对设备要求低，可以消耗SiC纤维生产过程中出现的短纤和废丝，满足大批量生产需求，且纤维与涂层均为SiC材质，在高温工况下不会出现因热膨胀差引起的涂层龟裂和脱离剥落现象。
