The invention provides a process for coating workpieces by plasma-induced chemical vapor deposition, in which a process gas is introduced into a coating chamber and a plasma is ignited by electromagnetic energy in at least one region of the coating chamber which adjoins the workpiece and in which the process gas is present, wherein the coating operation is monitored on the basis of at least one measured spectral parameter of the plasma, and the workpiece is removed in the event of a deviation from a desired range for the parameter.

Process and apparatus for the plasma coating of workpieces with spectral evaluation of the process parameters

The invention relates to a composite material (), to containers made therefrom and to a method for producing the composite material (), which comprises a substrate () and a coating () on the substrate (), wherein the coating () provides at least a first region () facing the substrate () and at least a second region () facing away the substrate (), and wherein the first region () comprises a barrier layer () and the second region () a passivation layer ().

PICVD coating for plastic containers

A coating apparatus is provided for simplifying the introduction and removal of workpieces into and from a reactor for plasma coating and to increase the throughput. The coating apparatus has a reactor with a moveable sleeve part and a base element, at least one sealed coating chamber being defined between sleeve part and base element when the latter two parts are fitted onto one another. The coating apparatus also has a device for introducing electromagnetic energy into the at least one coating chamber. The reactor has at least two coating places.

Multi-place coating apparatus and process for plasma coating

The invention relates to a method and an apparatus for the treatment of substrates, in particular for the coating of plastic containers on a rotary installation. A plurality of treatment devices are arranged on the rotor and pass through a plurality of process phases as a function of their angle position on the rotor. For at least one process phase, the angle position can be set variably as a function of the current rotational speed of the rotor.
