Abstract (en)

[origin: DE19957775C1] The invention relates to a method for modifying a wooden surface (7). An electrode (1) is arranged opposite the wooden surface (7) for modification and an alternating high voltage applied to the electrode (1), in order to cause a discharge (11), between the wooden surface (7) and the electrode (1), under atmospheric pressure. A dielectric layer between the electrode (10) and the wooden surface (7) to be modified is thus generated and the alternating high voltage applied with a frequency greater than 600 Hz.
