Preparation and Anti-oxidation Behavior of Si-C-B Self-healing Coating on C/SiC Composite
Source abstract
Abstract
采用化学气相沉积法（CVD）制备单质B和BC。分别对SiC涂层进行改性，在二维碳纤维增强碳化硅（2DC／SiC）复合材料表面制备SiC／B／SiC和SiC／BCx／SiC两种多层自愈合涂层，并利用扫描电镜对多层涂层表面和断面进行显微分析．700℃静态空气条件下氧化结果表明：CVD—B和CVD—BCx改性层氧化后生成的B2O3玻璃相可以较好地封填涂层微裂纹，氧化动力学受氧通过微裂纹和B2O3玻璃层的扩散共同控制；SiC／BCx／SiC-C／SiC复合材料氧化过程中氧化失重率更小，氧化10h后的强度保持率更高．
