Method and device for treating the surfaces of items

摘要

The present invention relates to a method and a device for treating the surface of objects, in particular strip material or deep-drawn material, in which the to-be-treated surface (2) of the object (1) is subjected to a barrier discharge which is generated between a first planar electrode (4) and a second planar electrode (5) in a discharge region (3) which is filled with a first gas or gas mixture, with a plasma-excited second gas or gas mixture which emits UV radiation being utilized as the second electrode (5). A surface treatment of greater efficiency and less duration including complete sterilization at low temperatures are achieved with the present method and the corresponding device.
