| 摘 要： | 在用混合磨碎法制备Ｂ４Ｃ／Ｃ复合材料的基础上，考察了不同条件对复合材料氧化失重速率的影响，然后讨论了上述各因素对复合材料抗氧化性能的影响机制，并对复合材料结构与其自愈合功能的性进行了分析，在此基础上建立了复合材料高温氧化过程的结构变化模型。

| Abstract: | A fter B4C /C composites were prepared by long -- time grinding methods,the effective factors such as content of B4C, oxidation temperature, 0xidation medium on the rate of weigh L -- loss of the composites were investigated' Then the mechanism that those factors influenced oxidation resistance of the composites was discussed and the correlation between structure and self - healing characterics was analyzed' Finally the structure mouls of the composites during the oxidation at high temperature wereconstructed' |
