An apparatus for treating the outer surface of a metal wire being moved through the apparatus along a direction of longitudinal extension of the metal wire has two electrodes arranged at a distance in the direction of longitudinal extension of the metal wire, a gas room being arranged between the outer surface of the metal wire to be treated and said electrodes, a dielectric shielding for said electrodes shielding said electrodes towards the metal wire, and an alternating voltage generator generating an alternating high voltage between said two electrodes to provide a dielectric barrier discharge in said gas room above the outer surface of the metal wire. The metal wire serves as an intermediate electrode between said two electrodes.
