| 摘要 |
The invention relates to a plasma coating system for coating or treating the surface of a substrate (3), comprising a working chamber (2) that can be evacuated and in which the substrate (3) can be placed, and comprising a plasma burner (4) for producing a plasma beam (5) by heating a process gas. The plasma burner (4) has a nozzle (41) through which the plasma beam (5) can exit the plasma burner (4) and can extend along a longitudinal axis (A) in the working chamber (2), wherein downstream of the nozzle (41) a mechanical delimiting device (12) is provided in the working chamber (2) and extends along the longitudinal axis (A) and protects the plasma beam (5) against a lateral, undesired penetration of particles. The invention further relates to a corresponding method.
