Thermal spraying - Wikipedia

Thermal spraying techniques are coating processes in which melted (or heated) materials are sprayed onto a surface. The "feedstock" (coating precursor) is heated by electrical (plasma or arc) or chemical means (coustion flame). Thermal spraying can provide thick coatings (approx. thickness range is 20 microns to several mm, depending on the process and feedstock), over a large area at high

Thermal Spray & Metalizing | Donaldson Industrial Dust

The thermal spray processes involve such heat that the process produces a very fine dust (fume), typically sub-micron in size and very uniform. Some of the materials used in thermal spray appliions have associated adverse health effects, and defined minimum exposure limits set for them, which necessitates effective dust collection.
