  • Patent number: 9688438
    Abstract: The method serves for the plasma treatment of container-like workpieces. The workpiece is inserted into an at least partially evacuable chamber of a treatment station. The plasma chamber is bounded by a chamber base, a chamber cover and a lateral chamber wall. The plasma treatment causes a coating to be deposited on the workpiece. The plasma is ignited by microwave energy. The coating consists at least of a gas barrier layer and a bonding layer arranged between the workpiece and the gas barrier layer. The gas barrier layer contains SiOx and the bonding layer contains carbon. The gas barrier layer is produced from a gas that contains at least one silicon compound and argon.

  • Patent number: 9169559
    Abstract: A method for the plasma treatment of a workpiece that includes inserting the workpiece into a plasma chamber and depositing, with the effect of a partial vacuum after plasma ignition, a coating on the workpiece by plasma treatment. Plasma ignition occurs by pulsed microwave energy, and alternating “on” phase times and “off” phase times from pulsed microwave excitation are provided by a control. During a beginning portion of the plasma treatment, a first portion of the coating is deposited. Subsequently, a quotient of the “on” phase times and the “off” phase times is increased to deposit a second portion of the coating, which has a different composition than the first portion of the coating. The quotient of the “on” phase times and the “off” phase times is then decreased to form a third portion of the coating, which has a different composition than the second portion of the coating.

  • Publication number: 20130264303
    Abstract: The method serves for the plasma treatment of workpieces. The workpiece is inserted into a chamber of a treatment station that can be at least partially evacuated. The plasma chamber is bounded by a chamber bottom, a chamber top and a lateral chamber wall. The plasma treatment involves depositing a coating on the workpiece. The ignition of the plasma is performed by microwave energy. The coating consists at least of a gas barrier layer and a protective layer. The gas barrier layer contains SiOx and the protective layer contains carbon. The protective is produced from a gas that contains at least a silicon compound and argon.

  • Publication number: 20130202814
    Abstract: The method and the device are used to plasma-treat workpieces. The workpiece is inserted into a chamber of a treatment station that can be at least partially evacuated. The plasma chamber is bounded by a chamber bottom, a chamber cover, and a lateral chamber wall. A coating is deposited on the workpiece by means of the plasma treatment. The plasma is ignited by pulsed microwave energy. Switch-on phases and switch-off phases of a microwave input are specified by a controller.
