Embodiment Construction

[0015] The single illustration shows a housing part 1 which is pot-shaped and has a planar bottom wall 2 and a cylindrical, surrounding housing wall 3 . The housing part 1 can have a circular, rectangular or polygonal cross-section. The housing part 1 is designed to be open on the side opposite the bottom wall 2 and thus serves as a receptacle for a pressure means 4 for surface elasticity in the form of a one-piece elastic material. The block is made, for example, of a preferably soft elastic foamed plastic.

[0016] On the side facing away from the bottom wall 2 , the elastic pressing means 4 are provided with a large-area recess which forms a receiving chamber 6 delimited by a surrounding edge 5 . An electrode element 7 comprising a planar electrode 8 which is surrounded on all sides by a planar and flexible dielectric 9 is inserted into the receiving chamber 6 which is open on one side. The dielectric 9 protrudes with an active surface 10 beyond the edge 5 of the pressing...

Abstract

The invention relates to an electrode arrangement for forming a dielectrically impeded plasma between an active surface (10) of the electrode arrangement and a surface acting as counter-electrode, having a flexible, planar electrode (8) that can be connected to a high voltage source (28) and having a planar, flexible dielectric (9) that forms the active surface (10) and is connected to the planar electrode (8) to form an electrode element (7), and completely covers the electrode (8) towards the surface to be treated. According to the invention the electrode arrangement has improved adaptability to irregular surfaces by means of a contact means (4) having surface elasticity for pressing onto the rear face of the electrode element (7) facing away from the surface, in such a manner that the electrode element (7), by local deformation, can automatically be adapted to irregularities of the surface.

Description

technical field [0001] The invention relates to an electrode assembly for forming a dielectric barrier plasma formed between an active surface of the electrode assembly and a surface acting as a counter electrode, the electrode assembly having: a flexible A planar electrode, which can be connected to a high voltage source; a planar, flexible dielectric forming the active surface, which is connected to the planar electrode to form an electrode element and which faces the to-be-treated The electrodes are completely covered superficially. Background technique [0002] It is known that the surface of workpieces, and also the surface of the skin, can be advantageously treated in different ways by means of plasma discharges. For subsequent surface treatments such as coatings, the workpiece surface can be activated so that the coating can adhere better. In addition, plasma discharges can be used to clean surfaces, for example to strip oil layers. [0003] In addition, the dielec...
