Certain metals, such as Copper, Iron, and Steel will oxidize with prolonged exposure to oxygen (air). Oxidization is oxygen reacting with the metal, causing it to rust. A layer of paint completely covers the metal, so it isn't exposed to air and thus cannot rust (until the paint wears away).
Painting will be a good option to prevent rusting.
through painting the metals are covered with paint coating which protects the oxidation.
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
Rusting , Corrosion & Looks
Yes, rusting is a very important problem for all iron structures.
It creates a protective layer between itself and the surrounding. Logic.
Under painting, or undercoating, is a coating added under the vehicle. It helps keep the underside of a car from rusting, and is especially helpful in snow or beach areas.
It is important to put your battery far away from moisture to prevent it from rusting.
Rusting of iron can be prevented by painting,oiling,greasing,galvanising,chrome plating,anodising or making alloys
Ships suffer a lot damage from rusting, despite paint, because they are always in the water. Other objects, such as cars, rust less because they get wet less.
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.
