This textbook discusses the latest advances in the corrosion of metals and related protection methods, and explores all corrosion-related aspects used in natural and industrial environments, including monitoring and testing. Throughout the textbook, the science and engineering of corrosion are merged to help readers perform correct corrosion assessments in both the design phase and plant management phase, and to define the optimal protection technique. In addition, the book addresses basic aspects of corrosion science, including the electrochemical mechanism, thermodynamic and kinetic aspects, the use of Pourbaix and Evans diagrams, and various forms of corrosion (from uniform to localised to stress corrosion phenomena); as well as the protection systems adopted to combat corrosion, including inhibitors, coatings and cathodic protection. Such basic knowledge is fundamental to understanding the "corrosion engineering" approach applied to the durability of metals immersed in water, buried in soil, exposed to the atmosphere, used in reinforced concrete, in the human body and in petrochemical plants, or at risk of high-temperature corrosion. A final chapter is dedicated to the use of statistics in corrosion. All chapters include exercises and practical examples to help students understand, predict, evaluate and mitigate corrosion problems. As such, the book offers the ideal learning resource for all students of corrosion courses in chemical, mechanical, energy and materials engineering at the graduate and advanced undergraduate level, as well as a valuable reference guide for engineers whose work involves real-world applications.
