Detonation Spraying of Protective Coatings

Detonation gun spraying, a technique of thermal spraying, achieves well-bonded dense protective coatings through ultrahigh velocity, medium temperature deposition of powders. The powdered feedstock materials range from metallic alloys to hard ceramics, enabling wear-resistant coatings to be formed. The science and technology of detonation spraying are reviewed relative to other associated methods of thermal spraying (e.g. plasma spraying). Special attention is centred on optimization methods for a range of engineering applications. The mechanism of formation of detonation-sprayed coatings are discussed. 176 ref.--AA
