Abstract

A plasma spray nozzle is provided. Owing to their high degree of wear, previous plasma spray nozzles were not suitable for the coating of components for which long coating times were necessary. The coating times may be reduced considerably by the triple injection of powder into the inner channel through the plasma spray nozzle.
