Material, useful in glazing for land transport, aquatic or air vehicle, preferably e.g. car windshield, glazing for building, interior installation or street furniture, comprises a glass substrate coated with a layer or a stack of layers

摘要

Material comprises a glass substrate coated with a layer or a stack of layers, and having a surface whose quadratic average roughness, determined by atomic force microscopy, according to the standard ISO 25178 is 4-15 nm, in which the distribution of height of the surface determined by atomic force microscopy having a maximum of more than 40% of the surface is below the height corresponding to the maximum of the distribution. An independent claim is included for manufacturing the material comprising preparing silicon oxycarbide layer on the surface of a mineral glass substrate, by chemical vapor deposition on at least a portion of the substrate surface by contacting the surface with a reactive gas stream containing ethylene, silane and carbon dioxide, at a temperature of 600-680[deg] C, the volume ratio of ethylene/silane is = 3.3.
