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.

Dr. Kamalan Kirubaharan Amirtharaj Mosas is a researcher at Alexander Dubcek University in Trencin, Slovakia, developing superalloy coatings for high-temperature applications. He has a background in ceramic coatings for corrosion and high-temperature applications, high entropy materials, ceramic matrix composites, and metal/ceramic thin films created using various physical vapor deposition (PVD) processes. He has prior experience with thermal evaporation, electron beam physical vapor deposition (EBPVD), pulsed laser deposition (PLD), and RF/DC magnetron sputtering systems. During the years 2019-2024, he received 8 sponsored projects from the defense and aerospace sectors, as well as one institutional funding for product development and commercialization. He has published 80 papers with more than 1000 citations and holds 9 Indian patents. He has served as a guest editor for Ceramics-MDPI, Coatings-MDPI, and Frontiers in Materials journals and a reviewer for a number of prestigious publications.

Assoc. Prof. Amirhossein Pakseresht is an associate professor and the head of the coating department at the FunGlass Centre for Functional and Surface Functionalized Glass at the Alexander Dubek University of Trencin in Slovakia. His research interests are plasma spraying, including splat morphology and novel thermal barrier coatings. He has also actively participated in multidisciplinary materials research, specifically surface science, anti-corrosion coatings, and composite materials. Recently, he received major grants for developing high entropy ceramics based TBCs and pyrochlore-based TBCs through plasma spray method.
