  • Arc-magnetron and the method of coating
    Patent number: 5160595
    Abstract: An arc magnetron is described in which an edge magnet arrangement is displaceable in the axial direction relative to a preferably fixedly mounted center pole permanent magnet so that a cathode sputtering process and/or an arc discharge process can be realized in dependence on the relative position of the edge magnet arrangement and the center pole magnet.
    Type: Grant
    Filed: May 16, 1991
    Date of Patent: November 3, 1992
    Assignee: Hauzer Holding B.V.
    Inventors: Fransiscus J. M. Hauzer, Wolf-Dieter Munz, Boudewijn J. A. M. Buil, Dietmar Schulze, Roel Tietema
  • Process and device for igniting an arc with a conducting plasma channel
    Patent number: 4906811
    Abstract: Process and device for creating a conducting channel for igniting of an arc in an environment with reduced pressure by means of high voltage. During ignition the conditions for ignition of the arc are optimized at a number of points between the parts where the arc has to be ignited. This optimization can comprise increasing of pressure and/or adding ignition-promoting gases.

  • Method and arrangement for mechanically moving of a magnetic field generating device in a cathode arc discharge evaporating device
    Patent number: 4902931
    Abstract: A method and device are provided to prevent grooves from occurring on a cathode surface of a cathode arc discharge evaporating device by adding a second movement to a first rotational movement of a magnetic field generator within the device, which enables the arc spot to scan a substantial portion of the cathode surface.

  • Cathode arc discharge evaporating device
    Patent number: 4849088
    Abstract: Cathode arc discharge evaporating device having a body of revolution as cathode. The target surface is arranged at the outside surface of the body of revolution. To control movement of the arc spot a magnetic field generating device is provided inside the body of revolution, which may be moveable with respect to the cathode.
