Reverse engineering intent

In corrosion theory and partly in practical corrosion engineering, the concept of electrode potential caimot be avoided. In order to understand corrosion and in many cases to take the appropriate steps to prevent it, a reasonably clear understanding of the term electrode potential is necessary. In this chapter it is the intention to establish such an understanding and present the formal quantitative expressions of electrode potentials, particularly under reversible or equilibrium conditions. Further, equilibrium diagrams of various metals are introduced. These diagrams show whether corrosion and other reactions are theoretically possible or not at given values of potential and pH of the environment.
