Coatings
Plasma coating uses plasma created by an electric arc burning within the nozzle of a plasma gun. The arc gas is formed into a plasma jet as it emerges from the gun nozzle. Powder particles are injected into this jet where they melt and then strike the surface at high velocity to produce a strongly adherent coating. Almost any material can be sprayed including metals, ceramics and plastics. The work piece remains cool because the plasma is localized at the gun. Applications for plasma sprayed coatings can be found in all industries - ranging from scuff resistant coatings on piston rings to thermal barriers on turbines and abrasion resistant coatings in the textile and paper industries.
