An adjustment-determining method includes obtaining a mathematical model relating an operating parameter of the deposition line to a quality function defined from a quality measurement of a stack of thin layers deposited by the deposition line on a transparent substrate; obtaining a value of the quality function from a value of the quality measurement measured at the outlet of the deposition line on a stack of thin layers deposited by the deposition line on a substrate while the deposition line was set so that an operating parameter had a current value; and automatically determining by the mathematical model an adjustment value for the current value of the operating parameter serving to reduce a difference that exists between the value obtained for the quality function and a target value selected for the quality function for the stack of thin layers.

Method and a device for automatically determining adjustment values for operating parameters of a deposition line

This transparent layered element () has two smooth outer main surfaces (A,A) and comprises: Each contact surface (S, S) between two adjacent layers of the element (), which are one a dielectric layer and the other a metal layer, or which are two dielectric layers having different refractive indices, is textured and parallel to the other textured contact surfaces.

Transparent element with diffuse reflection

A transparent substrate provided with a stack of thin layers includes an alternation of n functional layers having reflection properties in the infrared region and/or in solar radiation with n&#x2267;2 and of n+1 coatings including one or more dielectric layers, so that each functional layer is positioned between two coatings, the coatings and the functional layers are numbered according to their position with respect to the transparent substrate, the lower coating 1 is placed above the transparent substrate and below the functional layer 1, the intermediate coatings 2 to n are placed between two functional layers and the upper coating n+1 is placed above the functional layer n, wherein at least one of the upper or intermediate coatings 2 to n+1 includes at least one barrier coating including at least two barrier layers, one layer including silicon and one layer based on aluminum nitride.

Substrate coated with a stack of functional layers having improved mechanical properties

The subject of the invention is a material comprising a glass substrate coated on at least one of its faces with a thin-film multilayer comprising, starting from said substrate, at least one lower dielectric layer, at least one functional layer made of a metal or metal nitride, at least one upper dielectric layer and at least one layer of titanium oxide at least partially crystallized in the anatase form, said metal or metal nitride being based on Nb, NbN, W, WN, Ta, TaN or any of their alloys or solid solutions.

Material and glazing comprising said material
