CA 2422783
The invention concerns a method from cathode spray deposition of a coating with photocatalytic properties comprising titanium oxide at least partly crystallised in anastatic form on a transparent or semi-transparent support substrate, such as glass, vitroceramic, plastic. The substrate is sprayed under a pressure of at least 2 Pa. The invention also concerns the resulting coated substrate, wherein said substrate constitutes the top layer of a series of thin antiglare layers.
L'invention a pour objet un procédé de dépôt par pulvérisation cathodique d'un revêtement à propriétés photocatalytiques comprenant de l'oxyde de titane au moins partiellement cristallisé sous forme anatase sur un substrat porteur transparent ou semi-transparent du type verre, vitrocéramique, plastique. On réalise la pulvérisation sur le substrat sous une pression d'au moins 2 Pa. L'invention a également pour objet le substrat ainsi revêtu, où ledit revêtement constitue la dernière couche d'un empilement de couches minces antireflets.
