Thermal Spraying

Thermal Spraying is a coating process in which melted or heated materials are sprayed onto a surface. The feedstock is heated by electrical or chemical means. Thermal spraying can provide thick coatings (up to several mm) over larger areas and at higher deposition rates than other coating processes. Available coating materials include metals, alloys, plastics, ceramics and composites. These materials are fed to the spraying device in powder or wire form, heated to a molten or semimolten state, and accelerated toward the substrate to be coated in the form of micrometer-sized particles. The resulting coatings are created by the accumulation of numerous
