Hot-dip galvanization is a form of galvanization. It is the process of coating iron and steel with zinc , which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 450 °C (842 °F).
Galvanization (also spelled galvanisation) [1] is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing , in which the parts are coated by submerging them in a bath of hot, molten zinc.
Production of galvannealed sheet steel begins with hot dip galvanization of sheet steel. After passing through the galvanizing zinc bath the sheet steel passes through air knives to remove excess zinc, and is then heated in an annealing furnace for several seconds causing iron and zinc layers to diffuse into one another causing the formation of zinc-iron alloy layers at the surface.
This was the precursor of the modern hot-dip galvanizing. Sorel patent led to the industrial application and to the widespread use of the hot-dip galvanization process invented nearly one century earlier, in 1742, by the French physician and chemist Paul Jacques Malouin.
Compared to hot dip galvanizing, electroplated zinc offers these significant advantages: Lower thickness deposits to achieve comparable performance; Broader conversion coating availability for increased performance and colour options; Brighter, more aesthetically appealing, deposits
