However, in nature, the metal is not completely uniform and the electrolyte is not completely homogeneous, resulting in electrochemical corrosion cells that greatly overshadow this mild form of corrosion. 6.1.2 Concentration Cell Corrosion. This type of corrosion is caused by an electrochemical corrosion cell.
