Answer:

If the zinc coating is broken, the galvanized object remains protected against rusting because zinc is more reactive than iron and hence can be easily oxidized. Thus when zinc layer breaks down, the zinc continues to react and get oxidized. Hence iron object is protected.

Answer 2

Answer:

the galvanised article is protected against rusting even if the zinc coating is broken this is because when zinc is coated then a thin oxide layer of zinc is deposited on the article which always remains there so after broking the zinc coating the article gets protected.
