Abstract

A coating method for the internal coating of a hollow body which includes producing a plasma jet from a working gas, supplying at least one precursor material to the working gas and/or to the plasma jet, introducing the plasma jet through a first opening into an interior of the hollow body and depositing at least one reaction product of at least one precursor on an inner surface of the hollow body and/or on at least one layer arranged on the inner surface. The method is carried out at atmospheric pressure. Furthermore, the first internal coating takes place without an activation process directly after a production process of the hollow body, in which the hollow body is formed with the supply of heat.
