This book provides general coverage of the wide field of corrosion control. It is designed to help readers being initiated into corrosion work and presents each corrosion process or control procedure in the most basic terms. Since the first edition was published in 1970, there have been major advances and changes in the technologies used to combat corrosion damage. The best techniques available for detecting corrosion, determining the corrosion resistance of a material, or evaluating the efficacy of a control procedure serve as daily tools for attacking the problems faced by thousands of persons engaged in corrosion work. This book will foster a better appreciation for these procedures. As with the first and second editions of "Corrosion Basics: An Introduction," this third edition, also authored by Pierre R. Roberge, is intended to convey the scope of the field of corrosion prevention and control. It is important to realize the extent of the effort being made today in analyzing and combating corrosion. Much of the experience and many of the workable solutions developed in one area of corrosion work can be used to improve the control procedures of another area. While most people work in only one area of this total discipline, there is always the possibility that a shift in responsibilities or interest brings one to work in a completely different area of corrosion prevention and control.
