第三元素效应对TWIP钢表面在退火过程中内外氧化的影响

Impact of Third Element Effect on the Surface Internal and External Oxidations of TWIP Steel during Annealing

退火过程中钢板表面生成的氧化物对锌液在钢板表面的润湿性有很大影响,因此从理论和试验角度分析氧化物分布及其影响因素具有重要意义。在Wagner内外氧化理论的基础上,根据"第三元素效应"对一定退火环境下氧化物的内外氧化进行预测,并使用X射线光电子能谱(XPS)对实际退火过程中钢板表面生成氧化物的分布进行分析,进一步验证了理论预测方法和结果的准确性。

The oxides formed on the surface of steel plate during annealing have great impact on the wettability of the liquid zinc,so the analysis of the distribution and influencing factors using methods of theory and test are of great significance.On the basis of Wagner internal and external oxidation theory,the internal and external oxidation on the surface of steel plate in a certain annealing environment were studied according to the third element effect.Then the oxides formed on the surface of steel plate in the real annealing process were tested by X-ray photoelectron spectroscopy(XPS),and the accuracy of the prediction and experimental results were further verified.
