Abstract
The method of reduction comprises two successive steps. The first step consists in forming an electrolyte layer at the surface of the layer to be reduced which is an oxidized surface layer of a substrate. During the second step, the layer is reduced through the layer of electrolyte which is an ionic conductor for the ionizing species. The second step is carried out in a first variant by thermal reduction in a reducing atmosphere and in a second variant by exposure to a reducing plasma.
