The Tafel equation describes the behavior of one isolated reaction. In a corrosion system, we have two opposing reactions: anodic and cathodic. The Tafel equations for the anodic and cathodic reactions in a corrosion system can be combined to generate the

If the Tafel plot of both side reactions is known, one can use the two Tafel plots to find the theoretical corrosion current and corrosion potential. This is possible due to two facts: An immersed conducting sample has one potential at any instant and thu
