Method and plasma nozzle for generating a high voltage generated by means of high-frequency atmospheric plasma jet comprising a device in each case for the characterization of a surface of a workpiece

摘要

The invention relates to a method for the characterization of a surface of a workpiece, in which a by means of high-frequency high-voltage atmospheric plasma jet is generated and is directed onto the surface, in which the in the plasma jet in the region of the applied surface resulting light is analyzed, and in which the light intensity in at least one spectral range, as a measure for the concentration of at least one of the surface of the workpiece by means of action with the atmospheric plasma jet is determined detached substance. The method can be provided for the analysis of the surface itself or the quality of the treatment of the surface to be applied by the plasma jet.Furthermore, the invention also relates to a plasma nozzle for generating a high voltage generated by means of high-frequency, atmospheric plasma jet comprising a device for the characterization of a surface of a workpiece by means of an atmospheric plasma jet.
