| Sci-Tech Encyclopedia: Galvanizing |
The generic term for any of several techniques for applying thin coatings of zinc to iron or steel stock or finished products to protect the ferrous base metal from corrosion; more specifically, the hot dipping that is widely practiced with mild steel sheet and corrugated sheets. During dipping, molten zinc reacts with the steel to form a brittle zinc-iron alloy. For marine use, magnesium is added.
An electrolytic process (also called cold galvanizing or electrogalvanizing) is also used for wire, as well as for applications requiring deep drawing. An alloy layer does not form, hence the smooth electroplated coating does not flake in the drawing die. See also Metal coatings.
| Modern Science: galvanizing |
Placement of a thin coat of a metal such as zinc over iron or steel to protect the latter from rust. Galvanized metals typically appear shiny.
| Architecture: galvanizing |
The process of coating steel or iron with zinc by immersing it in a bath of molten zinc.
