Anode Film Resistance Effect on Cathodic Corrosion Protection

Application ID: 21101

This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products.

The model also includes secondary current distribution electrode kinetics on the protected steel structure, defining simultaneous metal dissolution and oxygen reduction (mixed potential).

This model example illustrates applications of this type that would nominally be built using the following products:
