Method and device for plasma-assisted chemical vapour deposition on the inner wall of a hollow body

摘要

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).
