HEY!!
HERE IS YOUR ANSWER,,
- The corrosion of metal can be prevented by coating very fine layer of Zinc metal on the surface of any metal.
- If coating of Zinc is removed or get broken from the surface then also that metal doesn't corroded because the more active Zinc metal spreads over the open surface and prevents it from corrosion.
HOPE IT HELPS....
THANKS....

Since zinc is more reactive than iron the zinc layer (which is thick) will start to corrode but iron does not
