What is it about?
Corrosion is basically the oxidation of metals, where electors are transferred between oxidant and reluctant. Therefore, corrosion is generally composed of redox reactions and should be analyzed from the viewpoint of electrochemistry. In this chapter, we describe the basic concept of electrochemistry and how various corrosion aspects can be explained by this discipline. We focus particularly on the equilibrium side because it could suggest possibilities that might be useful for corrosion predictions. The close relationship between redox reactions and corrosion are explained and stressed qualitatively and quantitatively.

Why is it important?
Corrosion is basically an oxidation reaction. Therefore, corrosion can be analyzed from the viewpoint of electrochemistry. Electrochemistry has two basic approaching ways - equilibrium and kinetics ways. In this chapter, we described the equilibrium side of corrosion basically.
Perspectives
Potenial and current. Two important parameters for corrosion measurements. Potential is the representative parameter for equilibrium theory and current for kinetics. This chapter, we explained the former side more.
