Abstract (en)

[origin: WO9946964A1] The invention concerns a method for treating the surface of an object using plasma generated by an electric discharge, during which said discharge is stabilised by confining said plasma in the form of a cord and surface treatment is carried out by sweeping the surface along the plasma cord. The invention aims at producing surface treatment using plasma with slight optical thickness, thereby only emitting very few ultraviolet rays.
