Mentioning reasons for metallic corrosion describe the remedies to prevent it.

The erosion reaction of any metal with water or moisture when it comes in its contact is called metallic corrosion and due to continuous exposure to moist air or water is the reason for metallic corrosion.

Remedies to prevent corrosion:

•Applying paint

It is easy and cheap method to prevent corrosion of iron. The body of a car windows or pillars can be protected against corrosion but it is essential to apply paint at regular intervals.

•Applying oil

Applying oil to the mechanical tools such as hammer, gardener scissors, etc. could be a method for protection of iron from corrosion due to presence of oil layer.

•Galvanisation

It is another method for prevention of iron from corrosion in which very fine layer of zinc metal is coated on the surface of iron. If zinc is removed from the surface of iron, it does not get corroded because zinc is more active metal which spreads and prevents corrosion. It is an effective method of prevention.

•Certain suitable chemicals which are called inhibitors can also be used so that they combine with the surface of metal by chemical bond and prevent corrosion.

•By making alloys which makes them more harder and stronger and prevents corrosion for e.g. steel.
