I. Fundamental Electrochemistry of Corrosion

－Equilibrium in Corrosion Phenomena－

Abstract

The definition and concept of electrode potential, equilibrium potential are simply explained on the basis of electrochemistry, considering not only thermodynamics but also electron energy.

The potential-pH diagram, which is derived from electrochemical and other equilibrium, is also introduced as the corrosion map which provides an over view of corrosion susceptibility of various metals.
