Prevents contact of Iron with oxygen and water
Painting will be a good option to prevent rusting.
Rusting of iron can be prevented by painting,oiling,greasing,galvanising,chrome plating,anodising or making alloys
It decreases rusting but doesn't totally prevent it.
by prevent the object away from the contact of oxygen. it can prevent an object from rusting.
its like humans wearing clothes, for the same reason..it protects them, and forms a barrier between the harsh elements (weather/rain)
Galvanising or painting both prevent iron from rusting. Painting is less expensive but also less permanent and the treatment needs to be repeated as the paint flakes off.
Coating prevent the iron from contacting air and moisture. So it prevents iron from rusting.
well according to me it is supposed to be coated with paint, so that it doesn't rust but there can be other ways too. painting is the best.
through painting the metals are covered with paint coating which protects the oxidation.
If they where painted
By preventing rusting of iron in bus not being sarcastic at all
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.
