This book addresses the recent trends in high-temperature coatings and their application to industrial components in extreme environments. It introduces the state of the art in coating materials and processes for high-temperature environments and identifies areas for improvement in materials selection, performance upgrades, design considerations, and manufacturing methods. It also includes fundamental studies involving modeling, creating coating architectures, coating preparation methods, and coating capability throughout a wide temperature range. The book looks at a variety of high-temperature coatings prepared through various synthesis processes such as thermal spraying, electron beam evaporation, and sol-gel methods. It covers the crystal structures, phase stability, and thermal and mechanical behavior of high-temperature coating materials made from ceramics, intermetallics, organosilicon polymers, cements, and other materials with great thermal stability.
