용융 Zn 합금 도금 강판
摘要：
용융 Zn 합금도금강판은, 강판과, 상기강판의표면에배치된용융 Zn 합금도금층과, 상기용융 Zn 합금도금층표면에배치된복합산화피막을가진다. 상기복합산화피막은, 상기용융 Zn 합금도금층의구성성분과바나듐을포함하고, 그러면서또 전면(全面)에서이하의수학식 (1)을만족한다. 수학식 (1)에있어서, S[Oxide]는, 상기복합산화피막의표면 XPS 분석강도프로파일에서, Zn의산화물에유래하는약 1022 eV를중심으로하는피크가나타내는면적이다. S[Hydroxide]는, 상기복합산화피막의표면 XPS 분석강도프로파일에서, Zn의수산화물에유래하는약 1023 eV를중심으로하는피크가나타내는면적이다.
摘要（英）：

Molten Zn alloy coated steel sheet, and steel sheet, and have the molten Zn alloy plating layer disposed on a surface of a steel sheet, a composite oxide film disposed to the molten Zn alloy plating layer surface. The composite oxide film, the molten Zn contains vanadium and composition of the alloy plating layer, yet should also satisfy equation (1) below the front (全面). According to equation (1), S [Oxide] it is, in the surface analysis of XPS intensity profile of the composite oxide film, the area of ​​the peak centered around 1022 eV derived from the oxides of Zn represents. S [Hydroxide] is, in the surface analysis of XPS intensity profile of the composite oxide film, the area of ​​the peak centered around 1023 eV derived from the hydroxides of Zn represents.
