This book sheds light on the development of the cold spray process in applications of additive manufacturing (AM) and repair/remanufacturing engineering. It covers the process fundamentals of different cold spray techniques, namely low pressure cold spray and high pressure cold spray process. Bonding mechanism and powder substrate interface are an important part of the book. The chapters present the recent developments in materials used in cold spraying for AM and various coating applications. The latest research in this area as well as possible avenues of future research are also highlighted as a way to encourage the researchers.

Dr. Sunil Pathak is specialized in gear engineering and advanced/hybrid manufacturing processes. He has been working in the field of gear engineering since last 9 years and advanced manufacturing for over 6 years. He has conducted extensive research on advanced finishing of gears. He possesses specialized skills in gear finishing, gear metrology (micro, and macro-geometry) and measurement of gear accuracy. Presently he has been working on machining of difficult-to- machine materials using advanced machining processes such as EDM and WEDM. He is also working in developing cold spray coatings as sustainable process for manufacturing of 3D additive manufacturing components and repair/remanufacturing engineering, where he has specially gained experience in materials and remanufacturing engineering. He has developed analytical models of manufacturing processes and optimizing parameters to achieve overall sustainability in manufacturing.Dr. Gobinda Saha is an Associate Professor and Director of Nanocomposites and Mechanics Laboratory at the University of New Brunswick, Canada. In recent past, Dr. Saha has led the R&D division at two successive nanocomposites manufacturing companies in conjunction with academic appointment at the University of Calgary, Canada. His focused research and innovation work in bio- and nanostructured materials and additive manufacturing is dedicated to serve as bridge building between industry and academia, on the divulsion of theoretical knowledge into applied solutions. Pertaining work in nanostructured materials has contributed to design, synthesis, testing, and commercialization of two surface protective coating systems for oil and gas industry, developed on the high velocity oxy-fuel and cold spraying methodology. Simultaneously, Dr. Saha's research in design, fabrication, processing, and characterization/testing of smart optical sensor reinforced FRP composites and modelling has contributed to the dissemination of knowledge through peer-review publication in over 50 research papers, two patents, as well as a strong supervision of graduate thesis research track record. Dr. Saha has given numerous invited talks on the topic of 'Nanostructured Cermet Composites and Biocomposites'. He has served as the Chair of ASME Composites & Heterogeneous Materials Technical Committee, as well the founding member of the Joint Canada-USA Regulatory Cooperation Council on developing strategies for nanomaterials including risk assessment and management and uses of industrial nanomaterials.
