Book excerpt: The text presents advances in the field of thermal claddings for protection against erosion, corrosion, and wear in hydraulic turbines, automobiles, agricultural equipment, power plant, chemical industries, and jet engines. It further discusses different cladding techniques such as electron beam, oxyfuel, arc welding processes, and microwave hybrid heating. It explains the mechanism for failure of materials and cladding and emphasizes the protection mechanism. This book: ·Discusses the design and simulation of thermal claddings and the use of algorithms to predict the process parameters and performance of developed clads using artificial intelligence and machine learning. ·Presents the tribological behaviour of novel wear-resistant thermal claddings for the components used in construction, mining, drilling, and hydropower plant. ·Showcases high-temperature oxidation, corrosion, and erosion-resistant thermal claddings for power plants, the automotive sector, and jet engines. ·Highlights the application of the thermal cladding process in remelting the existing surface to enhance the surface properties. ·Examines post-heat treatment procedures on thermal claddings for improving the microstructure and tribological properties. The text is primarily written for senior undergraduate, graduate students, and academic researchers in the fields of mechanical engineering, manufacturing engineering, industrial engineering, and production engineering.
