热浸镀Zn合金钢板及其制造方法
摘要：
本发明的热浸镀Zn合金钢板具有：钢板；以及配置于所述钢板的表面的热浸镀Zn合金层。所述热浸镀Zn合金层在整个面满足以下的式(1)。在式(1)中，S[Zn]是在所述热浸镀Zn合金层的表面的XPS分析的强度分布中、来源于金属Zn的以约1022eV为中心的峰所示的面积。S[Zn(OH)2]是在所述热浸镀Zn合金层的表面的XPS分析的强度分布中、来源于Zn(OH)2的以约1023eV为中心的峰所示的面积。。
摘要（英）：

This hot-dip Zn-alloy-plated steel sheet comprises: a steel sheet; and a hot-dip Zn-alloy-plated layer arranged on a surface of the steel sheet. The entire surface of the hot-dip Zn-alloy-plated layer satisfies the following formula (1): S[Zn(OH)2]/(S[Zn(OH)2]+S[Zn]) * 100 <= 40. In formula (1): S[Zn] is the area exhibited by a peak having a center at approximately 1022 eV ascribable to metallic Zn in an intensity profile in XPS analysis of the surface of the hot-dip Zn-alloy-plated layer; and S[Zn(OH)2] is the area exhibited by a peak having a center at approximately 1023 eV ascribable to Zn(OH)2 in an intensity profile in XPS analysis of the surface of the hot-dip Zn-alloy-plated layer.
