High-Entropy Alloy Coatings

High-Entropy Alloy Coatings: Fundamentals and Applications is a comprehensive overview of the exciting potential of HEA coatings. This book will cover the fundamentals, fabrication methods, applications, and recent advancements in this field, with concise chapters on each topic written by a team of experts. Part I concentrates on the fundamental principles, while Parts II, III, and IV are dedicated to coating type, fabrication methods, and applications of HEA coatings.

High-entropy alloys (HEAs) consist of multiple (five or higher) principal elements distributed in roughly equal atomic percentages. This makes them well-suited as coating materials for extreme operational conditions. HEA coatings have attracted considerable interest due to their remarkable mechanical and tribological properties and their resistance to high-temperature oxidation, as well as protective coating applications (against corrosion and wear), HEA coatings have diverse applications in several fields, including energy storage and conversion, electrocatalysis, biomedical, and nuclear sectors.

This book is written for senior undergraduate and graduate students, research students, engineers, and researchers in the fields of Materials Science, Mechanical Engineering, Metallurgical Engineering, Corrosion Engineering, Surface Science, and Coating Technologies.
