Effect of elemental additions on hot-dipping galvanization behavior

open access: yesCogent Engineering, 2023
Hot-dip galvanization is a common corrosion-prevention technique for steel structures. The steel is submerged in a molten zinc bath, which forms a zinc coating on the steel’s surface. This provides a barrier against the corrosive elements.
