| 摘要 |
The invention relates to a substrate (10), especially a transparent glass substrate, provided with a thin-film multilayer comprising a functional layer (40) having reflection properties in the infrared and/or in solar radiation, especially a metallic functional layer based on silver or on a metal alloy containing silver, and two coatings (20, 60), said coatings being composed of a plurality of dielectric layers (24, 26; 64), so that the functional layer (40) is placed between the two coatings (20, 60), the functional layer (40) being deposited on a wetting layer (30) itself deposited directly onto a subjacent coating (20), characterized in that the subjacent coating (20) comprises at least one dielectric layer (24) based on nitride, especially on silicon nitride and/or aluminum nitride, and at least one noncrystalline smoothing layer (26) made from a mixed oxide, said smoothing layer (26) being in contact with said superjacent wetting layer (30). |
