Disappearance Behavior of the Fe-Al Interface Layer of Galvanized Steel Sheets
The variation of aluminum content at the interface between the zinc coating and the steel substrate, which corresponds to the quantity of the Fe-Al interface layer, with dipping time in a molten zinc bath was measured quantitatively with inductively coupled plasma optical emission spectrometry. Comparing the aluminum content between the sample dipped in the Zn-0.14 mass%Al bath and that dipped in the Zn-0.18 mass%Al bath, it was found that the Fe-Al interface layer disappeared with linear relationship with dipping time in the Zn-0.14 mass%Al bath. This suggests that the disappearance behavior of the Fe-Al interface layer was dominated by an interface reaction.
