Abstract: A device for generating an atmospheric plasma beam for treating the surface of a workpiece includes a tubular housing with an axis, an inner electrode within the housing, and a nozzle assembly with a nozzle opening for discharging a plasma beam to be generated in the housing. The direction of the nozzle opening runs at an angle relative to the axis, and the nozzle assembly can be rotated about the axis. By the aforementioned device, disadvantages are at least partly eliminated and uniform treatment of the surface is achieved in that a shield surrounds the nozzle assembly, and the shield is designed to change the intensity of the interaction of the plasma beam to be generated with the surface of the workpiece depending on the rotational angle of the nozzle assembly relative to the axis. Also provided are a system and method for treating the surface of a workpiece.

Abstract: A method for depositing a plasma polymer layer in an atmospheric-pressure plasma on a metallic substrate, wherein the plasma is obtained by a discharge between two electrodes. At least one organic coating precursor compound is fed into the region of the relaxing plasma and is deposited on the metallic substrate as a plasma polymer layer. Nitrogen or a forming gas is used as a treatment gas and the at least one organic coating precursor compound is selected from various compounds. Also disclosed is an article, an electrode and a capacitor which utilize the method and include a metallic substrate having a surface and a plasma polymer layer on the surface. Also disclosed is a method for producing the electrode or for producing the capacitor, a battery cell or a lithium-ion accumulator which comprises the electrode.

Abstract: A nozzle assembly for generating an atmospheric plasma jet includes an inlet, through which the jet can be introduced into the nozzle assembly, and a channel connected to the inlet so that the plasma jet introduced is conducted through the channel. Multiple nozzle openings are provided in the channel wall along the channel, through which a plasma jet can exit the assembly. The cross section of the channel in the region of a nozzle opening is shaped in such a way that a virtual medial plane runs between a virtual first tangent plane of the cross section through the nozzle opening and a virtual second tangent plane of the cross section opposite thereto and parallel to the first tangent plane divides the cross section into a first cross-sectional area at the nozzle opening. The cross-sectional surface of the first cross-sectional area differs from the cross-sectional surface of the second.
