Thermal Spraying Coatings

About Thermal Spraying Coatings

Thermal Spraying Coatings are coating processes in which molten or semi-molten materials are propelled onto a surface. The coating materials in the form of powder, wire, or rod are heated by Electrical (Plasma or Arc) or Combustion Flame and converted to micrometer-size particles. Then the particles are accelerated towards substrates and create a coating.

Thermal spraying is used in a variety of coating processes including Plasma Spraying, HVOF Spraying, Arc Spraying, and Flame Combustion Spraying. These processes are also called Metalizing Spraying.

Coating quality is usually assessed by its porosity, oxide content, macro and micro-hardness, bond strength, and surface roughness. Generally higher particle velocity results in higher coating quality.
