This book presents the principles of plasma and heat spraying. It introduces plasma jet and the formation of plasma sprayed coatings. It explains the adhesion process and also presents standard methods for measurement according to DIN forms. Some case studies are presented for illustration.Introduction.- Plasma Jet.- Formation of Plasma Sprayed Coating.- Basic Properties of Plasma Coatings.- Adhesion of Plasma Sprayed Coatings to Basic Backplate.- Plasma Spraying Equipment.- Thermal Spraying.- Adhesion Tests.- Thermal Fatigue Tests.Juraj Ruzbarskì is an associate professor at the Technical University of Kosice.
