Abstract
The invention relates to a device and a method for the metallic coating of a work piece with a mobile coating lance (20), by means of which a metal plasma jet can be generated to create the coating consisting of metal particles. According to the invention, an extraction hood (30) is provided, which at least encloses an axial section of the coating lance (20) in a ring-shaped manner, and the extraction hood (30) has a ring-shaped holding unit (50), which is configured to take up the metal particles.

1-15. (canceled)
Device for metallic coating of a workpiece having a mobile coating lance, through which a metal plasma jet can be generated to form the coating of metal particles,
- wherein ambient air can be removed from the coating lance with an overspray of metal particles via a waste air pipe,
- wherein
- an extraction hood, which annularly encloses at least an axial portion of the coating lance, is provided to draw off the ambient air,
- the extraction hood and the coating lance are arranged on a mobile base carriage,
- the coating lance is mounted so that it can be moved on the base carriage at least in one direction,
- the extraction hood has, on the mobile base carriage, an annular holding unit which is designed for depositing of metal particles,
- the extraction hood has a cover hood and a bottom plate, which is arranged on a lower side of the cover hood, and
- the annular holding unit is arranged releasably on the bottom plate.
