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.
