Abstract: The invention relates to a method for plasma-assisted chemical vapour deposition for coating or material removal on the inner wall of a hollow body (42). The method involves introducing a gas lance (44) into the hollow body (42) and forming a cavity plasma (45) to form a plasma cloud arranged at the tip of the gas lance by applying an electric radio-frequency field to an RF electrode (41).

Abstract: The present invention relates to a method for applying a coating to workpieces and/or materials containing at least one readily oxidizable nonferrous metal or an alloy containing at least one readily oxidizable nonferrous metal. The method comprises the following steps: b) Pretreating the workpiece and/or material by plasma reduction c) Applying a cover layer by plasma coating in a plasma coating chamber (FIG. 4a).

Abstract: A gas supply system for a gas phase deposition reaction chamber, in particular a CVD gas phase deposition reaction chamber or a PECVD gas phase deposition reaction chamber, comprises a gas supply device which has at least one heating element for heating a deposition medium and transferring the deposition medium into the gaseous phase. Furthermore, the gas supply system comprises a gas feeding device for transporting the gaseous deposition medium from the gas supply device to the gas phase deposition reaction chamber, wherein the gas feeding device comprises a sealing element at the transition to the gas phase deposition reaction chamber. As a result, it is possible to provide a gas supply system for a gas phase deposition reaction chamber allowing a homogeneous feeding of even deposition media which are not present in gaseous form at room temperature into the reaction chamber.

Abstract: The invention relates to a method for the application of a coating to workpieces and/or materials, comprising the following steps: applying an adhesive layer; and applying a high-strength top layer by plasma coating.
