WebApr 4, 2024 · The term galvanization, as it applies to corrosion, was first used to describe the process of applying a coating of zinc to an iron surface when the process was simultaneously developed in France as well as in England in 1837. The method employed then was to manually dip iron sheets into a hot bath of molten zinc. WebDuring galvanizing, the iron in the material reacts with the molten zinc to form a series of zinc-iron alloy layers, which are covered by a layer of iron-free zinc. For most hot-rolled steels, the zinc-iron alloy portion of the coating will represent 50-70% of the total coating thickness, with the free zinc outer layer accounting for the balance.
