Answer 2

Answer:

Explanation:

Waterline corrosion:

Materials in contact with water may experience waterline corrosion, a form of oxidation. Waterline corrosion happens when a base material has a section in contact with water and another piece in contact with air. As a result, there is a difference in the amount of oxygen that comes into contact with the surface of the material above and below the waterline, which causes a corrosive reaction.

The difference in oxygen content between the atmosphere and the water causes waterline corrosion. This occurs because the part of the substrate that receives more oxygen (the area exposed to air) turns into a cathode, whereas the area that receives less oxygen (the area in contact with water) turns into an anode. Oxidation can take place thanks to the development of an anode and a cathode. The portion of the substrate submerged in water eventually corrodes and oxidizes as a result of this.

Hence Waterline corrosion is a type of Differential oxygen type of corrosion.
