Explain why iron articles are galvanized?

Hi,
 

Galvanization, or galvanisation, is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanization, in which parts are submerged in a bath of molten zinc. Galvanizing protects in two ways:
 

  • it forms a coating of corrosion-resistant zinc which prevents corrosive substances from reaching the more delicate part of the metal
  • the zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.

Hope this helps you! Thumbs up!

Iron objects r galvanized to prevent the process pf rusting.Galvanization is the process in which iron objects r immersed in molten zinc and then left to dry.So the zinc layer acts as a barrier b/w iron & the atmosphere containing water & oxygen.Thus galvanization prevents rusting of iron.
