Thermal Spray Powders

Thermal spraying techniques are coating processes in which melted or heated materials are sprayed onto a surface. The feedstock is heated by electrical (plasma or arc) or chemical means.

Thermal spraying can provide coatings from approximate thickness ranges, 20 micrometers to several mm. This varies depending on the process and feedstock. Coating materials available for thermal spraying include metals, alloys, ceramics, plastics and composites. They are fed in powder or wire form, heated to a molten or semimolten state and projected at high speeds towards substrates in the form of micrometer-size particles. The source of energy for thermal spraying is usually  combustion or electrical arc discharge. Resulting coatings are made by the accumulation of many sprayed particles.

Coating quality is usually measured by its porosity, oxide content, hardness, surface roughness and bond strength. Increasing paricles velocity, typically increase quality.
