  • Patent number: 12286705
    Abstract: The invention relates to a coating method and to a coating device for coating a body. A magnetron cathode having a target is arranged in the vacuum chamber. Electrical power is supplied to the magnetron cathode such that a plasma is generated and the target is sputtered in order to deposit a coating on the body. The electrical power is periodically supplied within a period duration T according to the HIPIMS method as cathode pulses, wherein each cathode pulse comprises at least two cathode sub-pulses and an intervening cathode sub-pulse break. In order to be able to deposit coatings having favorable properties in a particularly favorable manner by using the chopped HIPIMS method, a bias voltage is applied to the substrate to be coated with bias voltage pulses, wherein each bias voltage pulse comprises at least two bias sub-pulses and an intervening bias sub-pulse break.
