Difference between dry corrosion and wet corrosion
Dry corrosion |
Wet corrosion |
The corrosion occurs in dry condition is known as dry corrosion. | The corrosion occurs in wet condition is known as wet corrosion. |
Dry corrosion explain the absorption mechanism. | Wet corrosion explains the electrochemical mechanism. |
The corrosion takes place in the dry condition is uniform. | The corrosion takes place in the wet condition is not uniform. |
Dry corrosion is very slow process. | Wet corrosion is a fast process. |
Dry absorption occurs on the heterogeneous and homogeneous surfaces. | Wet corrosion occurs on heterogeneous surfaces only. |
Dry corrosion takes place when there is direct attack of chemical substance in the absence of the moisture . | Wet corrosion takes place when there is electrochemical attack occurs in the presence of the moisture or an conducting medium. |
The product after the corrosion accumulate at the place where the corrosion actually occurred. | The product after the wet corrosion accumulates at the cathode while the reaction is carried out at the anode that means at the opposite poles. |
