通过向铁基固溶体α相中添加不同含量Ni元素,运用SEM、EDS方法研究了Fe-Ni固溶体在液态金属锌中的腐蚀行为,腐蚀产物生成过程以及腐蚀层各相生长动力学规律。研究表明,腐蚀层厚度主要由ζ相层决定,Ni元素的添加抑制了柱状ζ相的异常长大,降低了铁基固溶体在液态金属锌中的腐蚀速率,提高了铁基固溶体在液态金属锌中的腐蚀性能。 The corrosion behavior of Fe-Ni solid solution in liquid zinc metal, the formation process of the corrosion products and the growth kinetics of the phases in the corrosion layer were studied by adding different amounts of Ni elements into the α phase of iron-based solid solution. The results show that the thickness of the corrosion layer is mainly determined by the ζ phase. The addition of Ni inhibits the abnormal growth of the columnar ζ phase, decreases the corrosion rate of the iron-based solid solution in the liquid zinc and increases the corrosion resistance of the iron- In the corrosion performance.
