Abstract :
The structure and the corrosion performance of Zn coatings formed by pack cementation and fluidized bed reactor at 250, 350, 380 and 400 °C have been studied. From this investigation, it turned out that these coatings are composed of two layers referring to γ-Fe11Zn40 and δ-FeZn10 phases of the Fe–Zn phase diagram. Furthermore, in the pack coatings, inclusions were detected, which are composed of Fe and Zn at almost equal concentrations. Concerning the corrosion, a mechanism of stress corrosion has been identified. The corrosion performance of the studied coatings is similar to that of the hot-dip galvanized coatings, although the deposition method is different.
