Hot-dip galvanizing (HDG) is a well-known process that increases the resistance of a steel strip to corrosion. Immersion of an automotive steel sheet in a galvanizing bath initiates a dissolution reaction. The flux of iron from the steel surface into the liquid zinc bath provides a driving force for the formation of an inhibition layer and the precipitation of dross particles. Such reactions involve the kinetics of nucleation and growth of intermetallic phases. This study addresses two main issues. First, the iron dissolution rate constant is governed by the solubility of iron in the liquid zinc under a metastable state between the pure bcc iron and the liquid phases. Secondly, a model for the nucleation and growth of precipitates can reveal the dynamics associated with intermetallic compound formation. The nucleation and growth model developed predicts that the inhibition layer covers 99.9% of the steel surface in 0.0011 second with the iron upersaturation of 0.56wt.% and the aluminum concentration of 0.20wt.% in a molten zinc bath at 460°C.
