Annealing of metal wire by atmospheric pressure discharge plasma

A manufacturing process of fine wire is mainly consisted of 3 following processes. 1) The drawing process, 2) The cleaning process, and 3) The annealing process. In this study, the possible application of atmospheric pressure dielectric barrier discharge plasma to the annealing of metallic wire was examined and presented. The main purposes of the study are as followings; 1) to investigate the annealing effect by using the plasma, 2) to examine the surface cleaning effect for the cylindrical object by the atmospheric pressure plasma. In the previous study, it was shown that the annealing of wire was possible by the plasma. Then, it was shown that surface cleaning was also possible by the plasma exposure. From these results, the possibility of the rationalization of fine wire manufacturing process was able to be shown.
