  • Physical vapour deposition coating device as well as a physical vapour deposition method
    Patent number: 10083822
    Abstract: The invention relates to a physical vapor deposition coating device (1), comprising a process chamber (2) with an anode (3) and a consumable cathode (4) to be consumed by an electrical discharge for coating a substrate located within the process chamber (2). The coating device (1) further includes a first electrical energy source (5) being connected with its negative pole to said consumable cathode (4), and a second electrical energy source (6) being connected with its positive pole to said anode (3). According to the invention, a third electrical energy source (7) is provided being connected with its negative pole to a source cathode (8) which is different from the consumable cathode (4). In addition, the invention relates to a physical vapor deposition method for coating a substrate.
