Title (DE) PLASMABRENNER
(EN) PLASMA TORCH
(FR) CHALUMEAU A PLASMA
Abstract:
(DE) Es wird ein Plasmaspritzgerät (1) vorgeschlagen, mittels dem insbesondere auch eine poröse Beschichtung auf einem Substrat herstellbar ist, wobei Qualitätsschwankungen der Porosität weitgehend vermieden werden sollen. Dies wird dadurch erreicht, daß ein Plasmaspritzgerät (1) mit einem indirekten Plasmatron (3) zur Erzeugung eines Langlichtbogens (36) mit einem seitlichen Injektor (28) versehen wird.
(EN) A plasma spray gun (1) is disclosed which also allows an in particular porous coating to be produced on a substrate while largely avoiding quality fluctuations in the porosity of the coating. For that purpose, a plasma spray gun (1) with an indirect plasmatron (3) for generating a long arc (36) is provided with a lateral injector (28).
(FR) L'invention concerne un pulvérisateur à plasma (1) qui permet également de réaliser un revêtement poreux sur un substrat tout en évitant largement les fluctuations de qualité de la porosité du revêtement. Pour ce faire, un pulvérisateur à plasma (1), doté d'un plasmatron (3) servant à produire un grand arc électrique (36), est pourvu d'un injecteur latéral (28).
