Modelling of the galvanizing reactions
Résumé
In continuous hot dip galvanizing, steel strip is immersed in a molten zinc bath containing small amounts of aluminium. A model has been developed describing the kinetics, of the galvanizing reactions that occur at the steel/liquid zinc interface (dissolution of iron, heterogeneous nucleation and growth of the intermetallic phase Fe2Al5Znx). The model has been validated using experimental data available in the literature for a three-second galvanizing treatment.
