Abstract

L’invention concerne un vitrage multiple comprenant au moins deux substrats séparés par au moins une lame de gaz intercalaire, le substrat constituant la paroi extérieure du vitrage comprend sur sa face tournée vers l’intérieur 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 à base d’oxyde de titane comprenant, tel que déposé, un gradient d’oxydation, 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 multiple glazing comprising at least two substrates separated by at least one interposed gas layer, the substrate constituting the outer wall of the glazing comprises on its inward-facing face 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, such that each functional metal layer is arranged between two dielectric coatings, characterized in that the stack comprises a titanium oxide-based coating comprising, as deposited, an oxidation gradient, located above and in contact with a silver-based functional metal layer, the part of the oxidation gradient coating in contact with the functional layer is less oxidized than the part of this coating further away from the functional layer.
