ABSTRACT:
The invention relates to a method of treatment, in particular cleaning and/or heating, for a metal substrate (1) fed in a substantially continuous manner through a vacuum chamber (3), having a treatment zone in which an electric discharge (10), i.e. a plasma, and a magnetic field are produced in a gas maintained at a pressure below atmospheric pressure between at least the substrate (1), acting as an electrode, and at least one counter-electrode (9) to enable the substrate (1) to be bombarded by the ions produced in the electric discharge (10). This method is characterised in that a confining magnetic induction field is produced entirely around the substrate (1) in the treatment zone so that the electric discharge (10) is also confined entirely around the substrate (1) inside this treatment zone by the confinement of electrons released in the electric discharge (10).
