CHEMICAL THEORY OF CORROSION

The different types of theories are:
i. Chemical Theory (Dry Theory)
ii. Electrochemical Theory (Wet Theory)

CHEMICAL THEORY OF CORROSION
Such types of Corrosion occur due to the chemical action of following liquid metal at high temperature on solid metal or alloy. This type of corrosion is common in devices used for nuclear power. The corrosion reaction involves one of the following
i. Dissolution of a solid metal by a liquid metal
ii. Internal penetration of the liquid metal into the solid metal.
