Ablation Resistance Properties of Ultra-high Temperature Composites C/C-SiC-ZrB2 by Slurry Impregnation Method
Source abstract
Abstract
采用浆料浸渍法引入ZrB 2 微粉作为耐超高温相, 以炭纤维为增强体, 以热解炭和SiC为基体, 制备了ZrB 2 含量不同的耐超高温C/C-SiC-ZrB 2 复合材料; 通过电弧风洞考核材料的抗烧蚀性能, 通过XRD、SEM和EDS分析材料的烧蚀机理。结果表明: 在Ma 6电弧风洞条件下, C/C-SiC-ZrB 2 复合材料的抗烧蚀性能优于C/C-SiC, 且随着ZrB 2 含量的增加, 抗烧蚀性能随之提高; 在高温阶段形成的ZrO 2 -SiO 2 玻璃态熔融层起到了抗氧化烧蚀的作用。
