Abstract
A surface treating apparatus which comprises a hollow cylindrical electrode and a counter electrode provided within the hollow cylindrical electrode, and a power supply for applying a potential between the electrode and the counter electrode to cause an atmospheric pressure plasma in the presence of a selected gas to generate within the cylindrical electrode is described. A method is also described, wherein a material to be treated is placed between the electrodes and a potential is applied therebetween to generate the plasma to effect the surface treatment of the material. The method and apparatus are very effective for surface treatment of axially symmetric substrates in the form of bars, tubes or fibers.
