Method and apparatus for coating an inner surface of a hollow endlessly geometry, in particular of a pipe

摘要

The invention relates to a method and apparatus for coating an inner surface of a hollow endlessly geometry, in particular of a tube, wherein the technical problem of providing a method and a device for coating an inner surface of a hollow endlessly geometry, in particular of a tube, which for a greater variety of cross sections, can be inserted, by a method and device is released, in which an at least one precursor of a gas mixture is introduced into the endlessly geometry, in which the endless geometry is guided by at least one electrode unit, in which an alternating electric voltage is applied to the electrode unit, in which, in the region of the electrode unit the gas mixture within the endless geometry at least partially converted into a plasma state, in which there is a reaction product by the plasma in the gas mixture of the precursor is produced and, in which the reaction product at the inner surface of the endlessly geometry is deposited.
