摘要(Abstract)：

为研究退火气氛露点对DP590热镀锌行为的影响,采用SEM,XPS分析了不同露点下DP590表面氧化物的形貌和类型以及不同露点下镀层横截面形貌和界面层形貌。结果表明,露点变化会影响DP590表面氧化物形貌,表面氧化物形貌随着露点在-10℃到-50℃变化,表面氧化物密度先升高再降低;露点变化不会影响DP590表面上Cr和Mn等氧化物的类型但是会影响Si的氧化物类型,随着露点变化Si的氧化物类型发生了改变;露点变化对氧化物的影响,后续会影响Fe、Zn之间的扩散,进而镀层横截面和界面层的组织结构,随露点从-10℃到-50℃变化,Fe、Zn扩散先加快后减慢,铁锌相先增多后减少。
