[yim336] Electrochemistry and Corrosion Science - Perez

The purpose of this book is to introduce mathematical and engineering approximation schemes for describing the thermodynamics and kinetics of electrochemical systems, which are the essence of corrosion science. The text in each chapter is easy to follow by giving clear definitions and explanations of theoretical concepts, and full detail of derivation of formulae. Mathematics is kept simple so that the student does not have a stumbling block for understanding the physical meaning of electrochemical processes, as related to the complex subject of corrosion. Hence, understanding and learning the corrosion behavior and metal recovery can be achieved when the principles or theoretical background is succinctly described with the aid of pictures, figures, graphs and schematic models, followed by derivation of equations to quantify relevant parameters. Eventually, the reader’s learning process may be enhanced by deriving mathematical models from principles of physical events followed by concrete examples containing clear concepts and ideas.
Example problems are included to illustrate the ease application of electrochemical concepts and mathematics for solving complex corrosion problems in an easy and succinct manner.
