Nanoscale supermultilayers structures demonstrate a new properties.
3D ion implantation.
3D Ion Implantation is a treatment method, according to which high energy ion flow on workpiece is formed directly from impulse discharge between vacuum chamber (anode) and the workpiece (cathode). Ions that are being accelerated in thin voltage drop near the cathode modify complex surface of the part. Electron beams are generated from surface of the cathode by falling ions and provide self-sustain of discharge via interaction with plasma. This method of treatment has significant advantages over ion beam systems, due to nonexpensive realization of the technological process and its simplicity. Our system can be combined with other ion and plasma assisted methods of treatment like magnetron and vacuum arc deposition as well as IBED methods.
