Abstract (en)
[origin: DE102005018926A1] The method involves producing an atmospheric plasma beam and directing the plasma beam onto a surface of a workpiece (56). The light produced in the plasma beam in the area of the surface is analyzed. Light intensity in a spectral range is determined as measure for the concentration of the material replaced from the surface by the impact of the plasma beam. The light intensity in one wavelength range is compared with another intensity. An independent claim is also included for a plasma nozzle for producing an atmospheric plasma beam with a device for characterization of a surface of a workpiece.
