摘要
合金内添加微量活性元素可以显著改善合金的抗高温氧化性能 .活性元素效应已在高温合金和抗高温氧化的防护涂层上得到大量应用 ,而其微观作用机制尚未完全明了 .本文综述了已有的活性元素微观作用模型 ,并分析了各种模型存在的缺点 ,对国内的研究成果也作了总结 .
The addition of reactive elements (RE) can have a significant effect on the oxidation behavior of the alloys of alumna and chromia former.Up to now,the mechanism through which RE plays the role has not been understood clearly.In this paper,the models developed previously to explain the RE effect have been reviewed,and comments on every REE model have been proposed.It is suggested that the change of oxide grain boundary and oxide/metal interface due to RE addition may be investigated carefully in the future.
