rust is caused by the interaction of the iron and the oxygen in the air. when iron is painted, there is a barrier between the iron and oxygen.
Iron can be prevented from rust not only by painting but also by coating the iron byzinc . But when we paint iron ,the hydrated oxide presented in the rust iron(Fe2O3.2H2O)can be prevented . Reaction of the iron with air ,water Etc can be prevented.
rusting of iron
rusting of iron . means when you put an iron object left open in moist air .... the moist air come into contact with the iron article and a brown flaky layer of iron oxide is formed on on the object. This is CORROSION of IRON .
How is iron gate is prevented from rusting
Rusting of iron is a chemical process, an oxydation reaction.
No, after painting iron can not make a strong bonding with concrete, the purpose of painting is the prevention of rusting but rusting process occurs in presence of carbon dioxide and moisture, when iron bars are sealed in concrete the rusting is not possible.
Prevents contact of Iron with oxygen and water
1. Rusting is an oxidation reaction of iron.2. The mass of an object increase after rusting.

Rusting of iron can be prevented by painting,oiling,greasing,galvanising,chrome plating,anodising or making alloys
Oxidation (rusting) of iron metal is the reaction of iron and oxygen
No, iron rusting is oxidation process
Its the moisture which causes rusting of iron
