Title (EN) PLASMA SPRAYING DEVICE
(FR) DISPOSITIF DE PROJECTION PLASMA
(DE) PLASMASPRITZVORRICHTUNG
Abstract:
(EN) The invention relates to a plasma spraying device, the torch head of which has a plasma channel (10) that extends between a cathode (3) and an anode (7). The plasma channel (10) is bounded by a plurality of neutrodes (4, 5, 6), which are electrically insulated from each other. A gap (26) extends between the frontmost neutrode (6) and the anode (7), which gap is divided into at least two sections (27, 29). There is a radial distance and an axial distance between the two sections (27, 29). An insulating disk (30, 31) is arranged in each of the two sections (27, 29).
(FR) La présente invention concerne un dispositif de projection de plasma dont la tête de combustion présente un canal à plasma (10) qui s’étend entre une cathode (3) et une anode (7). Le canal à plasma (10) est délimité par une pluralité de neutrodes (4, 5, 6) qui sont isolées électriquement les unes des autres. Entre les neutrodes (6) qui se trouvent le plus à l’avant et l’anode (7) s’étend un interstice (26) qui est subdivisé en au moins deux sections (27, 29). Entre les deux sections (27, 29) est formé un espacement radial et axial. Dans les deux sections (27, 29) se trouve un vitrage isolant (30, 31) respectif.
(DE) Es wird eine Plasmaspritzvorrichtung vorgeschlagen, deren Brennerkopf einen zwischen einer Kathode (3) und einer Anode (7) verlaufenden Plasmakanal (10) aufweist. Der Plasmakanal (10) wird von einer Mehrzahl von Neutroden (4, 5, 6) begrenzt, welche elektrisch gegeneinander isoliert sind. Zwischen der vordersten Neutrode (6) und der Anode (7) verlauft ein Spalt (26), der in zumindest zwei Abschnitte (27, 29) unterteilt ist. Zwischen den beiden Abschnitten (27, 29) besteht ein radialer und axialer Abstand. In beiden Abschnitten (27, 29) ist je eine Isolierscheibe (30, 31) angeordnet.
