| 摘 要： | 通过分析钴基超合金外扩散型铝化物涂层的高温氧化及退化行为 ,并采用近似方法推算 ,得出了这类涂层氧化和退化与时间的关系。研究表明 ,涂层外侧退化主要由氧化反应驱动力所控制 ,涂层的外侧退化速率正比于其氧化速率 ;而涂层的氧化寿期近似正比于其主体层厚的平方。运用氧化退化与时间的关系式 ,进行简便的辅助实验 ,即可预测出这类涂层的高温氧化寿命。

| Abstract: | The high-temperature oxidation and degradation behavior were analyzed for the aluminide coating on Co-base superalloy, and the relationship between the oxidation and life has been deduced for the coating. Using the obtained relationship formula, the high-temperature life of those coatings can be evaluated through the simple and convenient additional experiment. |
