Short-term formation kinetics of the continuous galvanizing inhibition layer on Mn-containing steels

Small additions of aluminum to the galvanizing bath results in improved coating ductility and adhesion through the formation of an Fe-Al interfacial (inhibition) layer which retards the formation of Fe-Zn intermetallic compounds. Understanding the interfacial layer formation mechanism, kinetics, and composition is very important in that it leads to better management of the galvanizing process and higher quality products. However, fundamental …
