Abstract: The present study explores the optimal methods for polishing NiTi and Ta stents. Electrochemical polishing was explored and several parameters were investigated including applied voltage, polishing time, and acid pickling prior to the polishing process. As a comparison, chemical polishing was also conducted. Both mechanical and electrochemical polishing of NiTi sheet materials were investigated to study the influence of electrochemical polishing on the surface composition of NiTi stents. Pickling was necessary prior to electrochemical polishing in order to remove the oxide films covering the stent surface. The surface quality of the NiTi and Ta stents significantly improved when the optimal condition for polishing was achieved.
