We all have heard that materials corrode when exposed to atmosphere or moisture. Let us know more on this.

Definition

The natural process that causes the transformation of pure metals to undesirable substances when they react with substances like water or air is called corrosion.

Advantages

Following are the advantages of corrosion:
i) Layer of protection: A layer of oxide is formed in surface corrosion which protects the inner metal from corrosion.
ii) Sacrificial anodes such as zinc is used as a preventive measure to stop corrosion of other metals.
iii) Galvanic corrosion: This type of corrosion occurs when two different types of metals are in electrical contact in an electrolyte where the more active metal tends to corrode.
