Answer 2

Anodic protection and Passivation are two methods for the prevention of corrosion.

In an Anodic Protection, a less active metal like tin is used to coat an iron alloy steel.

Tin does not corrode and the steel stays protected till the tin coating is there.

It is called anodic protection as the steel behaves as the anode of an electrochemical cell.

In the case of Passivation, a protective material's light coat like a metal oxide is used to produce a protective layer on top of a metal that helps in avoiding corrosion.
