对双元氧化剂引起二元固溶合金在无外氧化膜条件下 ,发生两氧化剂分立内氧化层的现象作了重新审视 .在摒弃前人某些假设并考虑可能出现的各种氧化膜结构的前提下 ,提出的理论模型可描述同时发生双元氧化与两者各自单独氧化时各氧化膜厚度之间的关系 ,双元氧化两内氧化层厚度比与它们的扩散系数的关系以及最活泼组元在界面富集的程度等 .藉所提理论还讨论了迄今已报道的有关研究结果 .
The phenomenon that binary oxidant causes the binary solid solution alloy to oxidize within two oxidizing agents under the condition of no external oxide film was revisited.While abandoning some of the previous hypotheses and considering the various oxide film structures The theoretical model proposed can describe the relationship between the simultaneous oxidation of the two oxides and the thickness of each oxide film when the two oxides are oxidized separately and the relationship between the thickness ratios of the two oxide inner oxides and their diffusion coefficients and the most active group The degree of meta-enrichment at the interface, etc. The research results reported so far are also discussed.
