摘要:
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.

The method and 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. The method process is optically monitored at least at times. In the optical monitoring, spectral lines of the radiation of the plasma above 500 nanometers are evaluated. Preferably, the evaluation is performed for frequencies above 700 nanometers.

The device is used for the plasma treatment of workpieces. The workpiece is inserted into a chamber (17) of a treatment station, wherein said chamber can be evacuated at least partially. The plasma chamber is delimited by a chamber bottom (29), a chamber cover (31), and a lateral chamber wall (18) and has a positionable gas lance (36). The gas lance is made of a dielectric at least in some regions.
摘要:
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 layer is produced from a gas that contains at least a silicon compound and argon.
摘要:
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. The relation between the duration of the switch-on phases and the duration of the switch-off phases is changed during the execution of the treatment process for a workpiece.
摘要:
The invention relates to a device for plasma treatment of workpieces. The workpiece is placed into a chamber of a processing station that can be at least partially evacuated. The plasma chamber is bounded by a chamber floor, a chamber cover, and a side chamber wall. The plasma chamber is coupled to a device for feeding and/or discharging process gases in a controlled manner. The plasma chamber is further disposed on a rotatable plasma wheel supported on a static base. At least one process gas channel is disposed in the region of the base, bounded at least in regions by a cover. The cover is implemented as part of the plasma wheel and comprises at least one connection opening to the process gas channel. The connection opening can be coupled to an inner chamber by a connecting channel and at least one control valve.
