Hot-dip galvanization - Wikipedia

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 449 °C (840 °F).

Hot-Dip Aluminizing of Low Carbon Steel Using Al-7Si-2Cu ...

Hot-dip aluminizing of low carbon steel was done in molten Al-7Si-2Cu bath at 690°C for dipping time ranging from 300 to 2400 seconds. Characterization of the intermetallics layer was done by using scanning electron microscope with energy dispersive spectroscopy. Four intermetallic phases, -Al7Fe2Si, -FeAl3, -Fe2Al5, and -Al2Fe3Si3, were identified in the reaction layer.

Galvanised Steel - GI Plates Manufacturer from Delhi

Galvanised Steel. Hot-dip galvanizing is the process of coating iron or steel with a thin zinc layer, by passing the steel through a molten bath of zinc at a temperature of around 860 °F (460 °C). When exposed to the atmosphere, pure zinc reacts with oxygen to form zinc oxide, which further reacts with carbon dioxide to form zinc carbonate, a dull grey, fairly strong material that stops ...
