INTRODUCTION
Hot-dip galvanizing of ferrous alloys is a coating operation involving dipping in a bath of molten zinc or zinc alloy at a temperature close to 460°C. It is applied to finished parts, sheets and wires coated by a continuous process.
Behind the generic name of hot-dip galvanizing, a wide variety of products of very different composition and structure currently exist, either because of the process itself (dipping of finished parts or continuous process), or because of the bath composition (aluminum from 0.05 to 55%, silicon, magnesium, etc.) or post-treatment (alloying, minimization of blooming, etc.). So there are hot-dip galvanizations and galvanized products.
