Abstract: An substrate is coated on one face with a stack of thin layers including at least one metallic functional layer. The stack includes a terminal layer that is the layer of the stack furthest from the face, which comprises at least one metal M2 that is a reducing agent in an oxide/metal pair exhibiting an oxidation/reduction potential ?2 and the terminal layer is in the metallic state. The stack also includes a preterminal layer that is the layer of the stack located immediately under and in contact with the terminal layer in the direction of the face, which comprises at least one metal M1 that is an oxidizing agent in an oxide/metal pair exhibiting an oxidation/reduction potential ?1 and the preterminal layer is in the at least partially oxidized state. The oxdiation/reduction potential ?1 is greater than the oxidation/reduction potential ?2.
