however, because numerical simulations taking into account all meaningful
parameters are rather onerous.
Corrosion cells not only are formed when two different metals are in contact
with each other but also can be the result of differences in the corrosive environment.
A typical example is differential aeration cells, which are due to differences in
accessibility of oxygen to the surface of a metal. Because the value of the corrosion
potential depends on the kinetics of the anodic as well as the cathodic partial
reactions, a different accessibility of oxygen results in a difference in corrosion
potential and hence in the establishment of a corrosion cell.
