This is the classic book on corrosion science and engineering-now in a valuable new edition. The ability to prevent failures by managing corrosion is one of the main global challenges of the twenty-first century. However, most practicing engineers and technologists have only a basic understanding of how they can actively participate in this urgent economic and environmental issue. Now, students and professionals can turn to this newly revised edition of the trusted Corrosion and Corrosion Control for coverage of the latest developments in the field, including advances in knowledge, new alloys for corrosion control, and industry developments in response to public demand. This fourth edition presents an updated overview of the essential aspects of corrosion science and engineering that underpin the tools and technologies used for managing corrosion, enhancing reliability, and preventing failures.Although the basic organization of the book remains unchanged from the previous edition, this new update includes: an introduction to new topics, including the element of risk management in corrosion engineering and new advanced alloys for controlling corrosion expanded discussions on electrochemical polarization, predicting corrosion using thermodynamics, steel reinforcements in concrete, and applications of corrosion control technologies in automotive, nuclear, and other industries a stronger emphasis on environmental concerns and regulations in the context of their impact on corrosion engineering and, a discussion of the challenge of reliability in nuclear reactors, stainless steels, the concept of critical pitting temperature, and information on critical pitting potential (CPP). Complemented with numerous examples to help illustrate important points, Corrosion and Corrosion Control, Fourth Edition enables readers to fully understand corrosion and its control and, in turn, help reduce massive economic and environmental loss. It is a must-read for advanced undergradua...
