A material includes a transparent substrate coated with a stack of thin layers including at least one silver-based functional layer, wherein the stack includes a protective coating deposited on top of at least one portion of the functional layer, the protective coating including: a lower protective layer having a thickness of between 1 and 10 nm, a central protective layer based on carbon graphite located on top of the lower protective layer, and an upper protective layer having a thickness of between 1 and 10 nm located on top of the central protective layer.

Glazing comprising a protective coating

A substrate is coated on one face with a thin-film multilayer including at least one metal functional film based on silver or made of silver having a thickness e of between 7 nm and 20 nm inclusive of these values, and two antireflection coatings. The antireflection coatings each include at least one antireflection film. The functional film is placed between the two antireflection coatings. The multilayer includes two discontinuous metal films each having a thickness e' of between 0.5 nm and 5 nm inclusive of these values. A lower discontinuous metal film is located between the face and the only or first metal functional film as counted starting from the face and an upper discontinuous metal film located above the only or last metal functional film as counted starting from the face.

Substrate equipped with a multilayer comprising a partial metal film, glazing unit, use and process

The invention relates to a substrate () coated on one face () with a multilayer of thin films () with reflective properties in the infrared and/or in the solar radiation band comprising a single functional metal layer (), in particular of silver or of a metal alloy containing silver, and two dielectric coatings (), said coatings each comprising at least one dielectric layer (), said functional layer () being disposed between the two dielectric coatings (), said multilayer furthermore comprising a single absorbing layer (), characterized in that said absorbing layer () is a metal layer having a physical thickness in the range between 0.5 nm and 1.5 nm, or even between 0.6 nm and 1.2 nm and is situated directly on said face () and directly under a dielectric layer of nitride not comprising any oxygen.

Substrate having a multilayer with thermal properties and an absorbing layer

A transparent substrate includes a stack of thin layers successively including, starting from the substrate, an alternation of three metallic functional layers, in particular of functional layers based on silver or on silver-comprising metal alloy, and of four antireflective coatings, each antireflective coating including at least one dielectric layer, so that each metallic functional layer is positioned between two antireflective coatings, wherein: the thicknesses of the metallic functional layers, starting from the substrate, increase as a function of the distance from the substrate, the second metallic functional layer is directly in contact with a blocking layer, referred to as second blocking layer, chosen from a blocking underlayer and a blocking overlayer, respectively referred to as second blocking underlayer and second blocking overlayer, the second blocking underlayer and/or the second blocking overlayer exhibits a thickness of greater than 1 nm.
