Failure of Hot-Dip Galvanized Steel Parts

Abstract The embrittlement of metals triggered by liquid zinc, has been known for about 140 years. William H. Johnson [1] stated that iron loses its forming capacity when dipped in melted zinc. Even today, this phenomenon still causes significant damages to hot-dip galvanized steel parts. Here, close attention should not only be paid to the composition of the molten zinc but also to the composition of the steel.
