Zusammenfassung:Generally it has been presumed that the high bond strength of detonation-sprayed coatings is related to the high kinetic energy stored in each particle during acceleration and released as heat on impact with the substrate. An investigation was conducted to define the basic technological parameters of detonation spraying that determine the energy state of the particles and consequently the conditions of coating formation. Relationships between adhesion strength and the technological parameters of detonation spraying and some of the properties of the materials are obtained. The influence on adhesion strength of substrate surface plastic deformation by particle impact is demonstrated. The possibility of a mutual influence of the powder particles on coating formation is also discussed.
