Question

What are the advantages of corrosion?

Answer 1

Corrosion

• Corrosion is one of the most common phenomena in our everyday life.
• When some metals, such as iron, are exposed to moist air for a long period, their surfaces corrode. This is referred to as corrosion.

Advantages of corrosion

• Galvanic corrosion:-This happens when two distinct metals come into electrical contact with an electrolyte and in this case, the more active metal may corrode.
• Surface corrosion results in the formation of an oxide layer, which protects the inner metal from corrosion.
• Some metals, such as zinc, are used as sacrificial anodes to protect other metals from corrosion.
