Vacuum arc evaporator in reactive mode.

The Physical vapor deposition processes (PVD) allow the deposition of high-quality tribological and functional layers in the thickness range from a few nanometers to several tens of micrometers. For this purpose, processes ranging from high-rate vapor deposition to highly activated plasma processes as well as their combinations are available at the Fraunhofer IWS. A particular focus is on the extensive use of arc discharges as the most effective source of high-energy steam jets.
