Corrosion and Its Prevention - 2

In electrochemical corrosion, corrosion occurs at anode but rust is deposited at cathode.

Dry corrosion is a slow process while wet corrosion is a fast process.

In electrochemical corrosion, corrosion does not depend on the size of the anodic part of the metal.

Dry corrosion involves direct attack of the chemicals on the metal surface.
