提出了一种描述在双氧化剂(X-Y)中、且生成有外氧化膜(AY_n)的情况下,二元合金(A-B)的腐蚀模型,并利用该模型对Fe-Cr合金的腐蚀动力学实例进行了分析。表明该模型的预测可信,而氧化剂在合金中的实际扩散路径复杂且尚难预见是导致内氧化区厚度的理论计算值与实验测定值之间存在较大偏差的主要原因。
A corrosion model of a binary alloy (AB) is described in the case of a double oxidizer (XY) and an outer oxide film (AY_n) is formed, and an example of the corrosion kinetics of the Fe-Cr alloy Analyzed. It is shown that the prediction of this model is credible, and the fact that the actual diffusion path of oxidant in the alloy is complex and difficult to predict is the main reason for the large deviation between the theoretical calculated value and the experimental value.
