Abstract
Bisherige Plasmaspritzdüsen sind durch den hohen Verschleiß nicht geeignet für die Beschichtung von Bauteilen, bei denen lange Beschichtungszeiten notwendig sind.Previous plasma spray nozzles are not suitable due to the high wear for the coating of components where long coating times are necessary.
Durch die dreifache Injektion von Pulver in den Kanal (4) durch die Plasmaspritzdüse (1) können die Beschichtungszeiten erheblich verhindert werden. By the three-time injection of powder into the channel (4) through the plasma spray nozzle (1), the coating times can be significantly prevented.
