High Current Arc

 CAD Zeichnung - HCA

A system for surface coating hard-drives with a 1.5 nm carbon layer was developed together with Arc Precision GmbH. The process relies on vapor of carob inside a vacuum. The energy is produces with a pulsed high current discharge (HCA source). The plasma is filtered with a magnetic arc and produces very thin and homogenous carbon layers on the target surface.

The length of a production cycle takes about 2 seconds. The surface coating itself takes less than a second.

Targetwechseler The coated material is deposited from a carbon target. A target is used up after about 30 minutes and can then be exchanged automatically during a running process. This exchange does not slow down the speed of the production cycle nor does it degrade the vacuum.

The system which was developed by Arc Precision and IWS together with the power supply from aixcon is ready for production processes.
aixcon delivers the following components:

  • HCA pulsed current source (5000A, 50kW)
  • contactless ignition
  • power supply for the filter arc (1000A, 20V)
  • control of drives (target exchange) and valves (4 drives, 30 valves)
  • complete software control interface
  • remote logging and support

Arc Precision won for this development the innovation Award of Berlin-Brandenburg in 2007.
