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 two kinds of B4C-SiC / C composite samples BS2020 and BS1530 without oxidation and preoxidation at 1200 ℃ for 1h was investigated at 800 ℃, 1000 ℃ (dry air) and 1000 ℃ humid air. The results showed that BS1530 had good oxidation resistance at 800 ℃ (dry and humid air), BS2020 at 800 ℃ (In dry air) and 1000 ℃ (dry and humid air) oxidation process of self-healing oxidation were significantly improved.
