This book provides an in-depth exploration of high entropy materials (HEMs) as coatings, looking at their fundamentals, synthesis methods, properties, and industrial applications. HEM-based coatings offer remarkable potential for next-generation structural components due to their tunable physical and chemical properties, including enhanced hardness, wear resistance, corrosion resistance, and thermal stability. Covering both high entropy alloys (HEAs) and high entropy ceramics (HECs), this book offers a comprehensive guide to their processing, characterization, and industrial uses in fields such as aerospace, automotive, and energy. Key topics include advanced synthesis methods, thermal and environmental barrier coatings, tribological properties, failure mechanisms, and the role of machine learning in optimizing HEM-based coatings. Written by leading experts, this book bridges the gap between fundamental research and industrial applications, providing scholars, researchers, and industry professionals with a valuable reference for advancing the field of high entropy material-based coatings.
