摘要:
The invention relates to a transparent substrate, in particular glass substrate, provided with a thin-film stack including at least one metal film with properties in the infrared, in particular a low-emissivity one, arranged between two coatings which each include at least one anti-reflection film based on dielectric material, and at least one protective film based on a sacrificial metal or a partially or fully oxidized sacrificial metal or a sacrificial metal alloy placed between the said metal film and one of the said coatings. According to the invention, the film placed directly below and/or above the said metal film contains at least one of the noble metals Pd, Au, Ir, Pt and Rh. The low-level addition of one or more of these metals to the others, namely the film placed below and/or above the metal film, leads to an increase in the chemical stability and the hardness of the thin-film stack.
摘要:
A layer stack for the surface coating of transparent substrates, in particular panes of glass, has at least one metal oxide composite layer produced by reactive cathodic sputtering and contains Zn oxide and Sn oxide. Relative to the total amount of metal, this metal oxide composite layer contains from 0.5 to 6.5% by weight of one or more of the elements Al, Ga, In, B, Y, La, Ge, Si, P, As, Sb, Bi, Ce, Ti, Zr, Nb and Ta. In a layer stack which has a silver layer as a functional layer, the metal oxide composite layer may be used as an upper and/or lower antireflection layer, as a diffusion barrier layer, as a sublayer of an antireflection layer and/or as an upper cover layer.

The invention is a transparent substrate provided with a multilayer stack having thermal properties, especially solar-control or low-emissivity properties. The stack comprises at least one silver-based functional layer surrounded by at least two coatings made of dielectric material, with the presence of thin metal layers between the functional layer and at least one of the coatings made of dielectric material. A preferred stack is D1/ZnO/Ag/AlM/D2/ZnM′O, with AlM representing an aluminum alloy, ZnM′O a mixed oxide of zinc and at least one other metal, with D1 and D2 being a layer or a superposition of layers comprising at least one layer made of a metal oxide, silicon nitride, metal nitride or made of a mixed silicon/metal nitride.
