Otherwise the iron will rust and eventually disintegrate and become unusable
to protect iron (or other metals from rusting).
Zinc has a greater resistance to corrosion than iron does, however it will still eventually corrode away, leaving the iron surface exposed. Its main purpose is to prolong the resistance of iron by rusting instead of it.
Ashoka pillar has a layer of crystalline iron hydrogen phosphate which protect it from rusting.
I'll give a non chemist answer but a wise answer... logically, you are covering it with a mixture (correct this If Im wrong), preventing it to have contact with the oxygen in the atmosphere. Therefore preventing the iron to oxidize :)
Rusting is a term adequate only for iron and iron alloys.
Paint or enamel can protect iron from rusting.
to protect iron (or other metals from rusting).
Try covering it in Zinc
no
This metal is zinc (Zn).
ZINC :)
Cobalt and Thorium
Zinc doesn't rust; zinc protect iron (and alloys) from rusting.

rusting of iron
iron bending different from iron rusting
