Difference between Dry Corrosion and Wet Corrosion

	Dry corrosion	Wet corrosion
1	It occurs in dry condition.	It occurs in wet condition.
2	If the corrosion takes place due to direct chemical attack (in the absence of moisture), corrosion is known as dry corrosion.	If the corrosion takes place due to electrochemical attack in presence of moisture or a conducting medium ,corrosion is known as wet corrosion
3	Explained by absorption mechanism	Explained by electrochemical mechanism
4	It occurs on both heterogeneous and homogeneous surfaces.	It occurs only on heterogeneous metal surfaces.
5	Corrosion is uniform.	Corrosion is not uniform.
6	It is a slow process.	It is a fast process.
7	Corrosion products accumulate at the place where corrosion occurs.	Corrosion take place at anode but products accumulate near the cathode.
