Advances in Thermal Spraying contains the proceedings of the Eleventh International Thermal Spraying Conference held in Montreal, Canada, on September 8-12, 1986. The papers explore technological advances in thermal spraying and the related field of surfacing by welding. This book is comprised of 97 chapters divided into 16 sections and begins with a discussion on the applications of thermal spraying in the power generation industry, with emphasis on the use of thermal coatings to protect boilers against corrosion. The following chapters focus on thermal spraying as applied to low-pressure processes; carbide coatings; properties of coatings such as aluminum bronze coatings; and control and automation of the thermal spraying process. The reader is then introduced to ceramic powders and coatings used in thermal spraying; quality assurance of plasma spray powders; and applications of thermal-sprayed coatings to protect against corrosion and wear. The remaining sections consider arc spraying; post-deposition treatment of plasma-sprayed coatings; and miscellaneous applications of thermal spraying, including insulation of diesel engine combustion chambers. This monograph will be of value to materials scientists, metallurgists, mechanical engineers, and those in fields ranging from physics to corrosion science and metallography.

Dr. Sam Stuart is a physiotherapist and a research Fellow within the Balance Disorders Laboratory, OHSU. His work focuses on vision, cognition and gait in neurological disorders, examining how technology-based interventions influence these factors. He has published extensively in world leading clinical and engineering journals focusing on a broad range of activities such as real-world data analytics, algorithm development for wearable technology and provided expert opinion on technology for concussion assessment for robust player management. He is currently a guest editor for special issues (sports medicine and transcranial direct current stimulation for motor rehabilitation) within Physiological Measurement and Journal of NeuroEngineering and Rehabilitation, respectively.
