Plasma-PVD (Plasma-Physical-Vapour Deposition)

The process of industrial plasma surface technology is a plasma-physical process for the deposition of almost all metals and alloys as well as their oxides, nitrides and carbides. PVD processes are used both to refine materials and surfaces of conventional products by coating and to realize new products that exploit special physical properties of thin layers. The first group of users includes wear and corrosion protection coatings on tools and highly stressed components, decorative coatings on consumer goods, barrier coatings on packaging films and optically effective coatings on glass. The second group includes microelectronic components, flat panel displays, and magnetic and optical data storage disks (e.g. CDs).

PVD processes are generally classified according to the type of generation mechanism:

  • Vacuum arc evaporation
  • Electron beam evaporation
  • Resistive evaporation
  • Hollow cathode evaporation
  • Low voltage arc evaporation
  • Sputtering Process
  • Ion plating

The given parameter window represents typical operating conditions. Processes with shorter treatment time, at higher pressure and other temperatures are basically possible.

Pressure: 0.01 - 1 Pa
Temperature: 50 - 550 °C
Treatment time: hours
Plasma excitation: Direct current, pulsed direct current, alternating current in medium frequency (kHz), high frequency (MHz).
