Method and installation for treating a metal part surface

摘要

In this method for the surface treatment of a metal part (12) for the purpose of deoxidizing it and/or cleaning it, a sealed chamber (16), in which the part to be treated is placed, is filled with a low-pressure reducing gas mixture, a static magnetic field is created in a region of the chamber (16) separate from the region in which the part (12) to be treated is placed and the gas mixture is excited by means of an electromagnetic wave injected into the chamber (16) so as to generate a treatment plasma in the gas, the intensity of the static magnetic field corresponding to electron cyclotron resonance established in the chamber in a distributed manner.
