Title (EN) COATINGS HAVING CONTROLLED ROUGHNESS AND MICROSTRUCTURE
(FR) REVÊTEMENTS PRÉSENTANT UNE RUGOSITÉ ET UNE MICROSTRUCTURE CONTRÔLÉES
Abstract:
(EN) An article includes a glass, glass-ceramic or ceramic substrate including a primary surface. A functional coating is disposed over the primary surface of the substrate. The coating includes a first portion disposed over the primary surface. One or more interrupting layers are disposed over the first portion. A second portion is disposed over the one or more interrupting layers. The one or more interrupting layers includes a microstructure different than one of the first and second portions and the coating has an average optical transmittance greater than about 10% over the visible wavelength range from about 450 nm to about 650 nm.
(FR) L'invention concerne un article comprenant un substrat en verre, en vitrocéramique ou en céramique présentant une surface principale. Un revêtement fonctionnel est disposé sur la surface principale du substrat. Le revêtement comprend une première partie disposée sur la surface principale. Une ou plusieurs couches d'arrêt sont disposées sur la première partie. Une seconde partie est disposée sur la ou les couches d'arrêt. La ou les couches d'arrêt comprennent une microstructure différente de celle des première et seconde parties et le revêtement présente une transmittance optique moyenne supérieure à environ 10 % sur la plage des longueurs d'onde de la lumière visible allant d'environ 450 nm à environ 650 nm.
