摘要
考察了未经和经过1200℃，1h氧化预处理的两种B4C－SiC／C复合材料样品BS2020和BS1530在800℃、1000℃（干燥空气）及1000℃潮湿空气中的氧化行为。结果表明：经过1200℃氧化预处理后，除了BS1530在800℃（于燥空气）氧化过程的自愈合抗氧化性改善程度有限外，BS1530在1000℃（干燥和潮湿空气）、BS2020在800℃（于燥空气）和1000℃（干燥和潮湿空气）氧化过程中自愈合抗氧化性均得到明显改善。
The oxidation behavior of the composites with or without preoxidation treatment at 120℃ for 1h was investigated at 800℃ and 1000℃. The results show that the preoxidation treatment has obviously improved the self - healing properties of composites BS2020 and BS1530 during oxidation at 800℃ in dry air and at 1000℃ in both dry and moisture air with relative humidity 80% except for that of composites BS1530 at 800℃.
