Abstract

Thermal spray is a materials processing technique used to deposit coatings to provide improved wear, corrosion, and/or thermal protection for engineering components. Thick (>10 {micro}m) thermal spray coatings are made up of individual solidified splats formed by the impact of molten and semi-molten particles on a substrate. The temperature, velocity, and flux density of spray particles impacting the substrate controls the microstructure of the resulting coating and determines its ultimate performance. In-flight measurement of thermal spray particles is thus a powerful means to achieve reproducible, high quality thermal spray coatings.
