Plasma Spraying of Metallic and Ceramic Materials D. Matejka, Institute of Materials and Mechanics, Slovak Academy of Sciences, Bratislava, Czechoslovakia and B. Benko, Faculty of Mechanical Engineering, Slovak Technical College, Bratislava, Czechoslovakia Plasma spraying of metallic and ceramic powders is one of the many areas of thermal spraying technology which has developed rapidly in recent years. This book describes the theoretical principles of plasma spraying as well as practical applications. The physical and mechanical properties of sprayed coatings are discussed, as well as methods for their evaluation. The book also includes guidelines on choosing the appropriate spraying powder for a particular industrial application and attention is paid to the problems of the bonding of sprayed coatings to the substrate. The technological process of spraying flat, rotatory and internal surfaces is also discussed and the book is concluded with a section on the safety aspects of plasma spraying and reference to the hazards.
