This book describes recent advances in plasma spraying. It is divided into two sections - theory and applications. Sophisticated experimental techniques, diagnostics, theoretical models and computer simulations are presented which will not only improve the understanding and uses of the spraying process but also help to increase the reliability factor of the manufacturing components. Applications that are metallurgical, aeronautical, automobile, chemical etc. are shown. For the first time, applications that include silicon for solar cells, magnets and superconductors are discussed. Advanced graduate students in materials science and engineering, research scientists, engineers and industries involved in plasma spray applications will benefit from this book.
