WHY DOES THE GALVANISED ARTICLE DO NOT GET CORRODED EVEN WHEN THE ZINC COATING IS BROKEN

Asked by  | 23rd Mar, 2008, 10:02: AM

Expert Answer:

the galvanised article is protected from rusting even when Zn coating is removed by a thin film of oxide naturally formed on the surface of iron as Zn is more active than iron
