<p>The invention relates to a glazing comprising a transparent glass substrate containing ions of at least one alkali metal, and a transparent layer of silicon oxycarbide (SiOxCy) having total thickness E with (a) a carbon-rich deep area extending from depth P3 to depth P4, where the C:Si atomic ratio is greater than or equal to 0.5, and (b) a superficial area having a low carbon content, extending from depth P1 to depth P2, where the C:Si atomic ratio is lesser than or equal to 0.4, with P1 < P2 < P3 < P4, and (P2-P1) + (P4-P3) < E the distance between Pi and P2 representing between 10 and 70% of total thickness E of the silicon oxycarbide layer and the distance between P3 and P4 representing between 10 and 70% of total thickness E of the silicon oxycarbide layer.</p> |
