Abstract

L’invention concerne un Matériau comprenant un substrat transparent revêtu d’un empilement de couches comprenant au moins une couche métallique fonctionnelle à base d’argent et au moins deux revêtements diélectriques, chaque revêtement diélectrique comportant au moins une couche diélectrique, de manière à ce que chaque couche métallique fonctionnelle soit disposée entre deux revêtements diélectriques, caractérisé en ce que l’empilement comprend un revêtement comprenant un gradient d’oxydation à base d’oxyde de titane situé au-dessus et au contact d’une couche métallique fonctionnelle à base d’argent, la partie du revêtement à gradient d’oxydation en contact avec la couche fonctionnelle est moins oxydée que la partie de ce revêtement plus éloignée de la couche fonctionnelle.The invention relates to a Material comprising a transparent substrate coated with a stack of layers comprising at least one silver-based functional metal layer and at least two dielectric coatings, each dielectric coating comprising at least one dielectric layer, so that that each functional metal layer is placed between two dielectric coatings, characterized in that the stack comprises a coating comprising an oxidation gradient based on titanium oxide located above and in contact with a functional metal layer based silver, the part of the oxidation gradient coating in contact with the functional layer is less oxidized than the part of this coating further from the functional layer.
