Abstract
The invention relates to a glazing comprising a transparent glass substrate containing ions of at least one alkali metal and a transparent layer made of silicon oxycarbide (SiOC) having a total thickness E with (a) a carbon-rich deep zone, extending from a depth Pto a depth P, where the C/Si atomic ratio is greater than or equal to 0.5, and (b) a carbon-poor surface zone, extending from a depth Pto a depth P, where the C/Si atomic ratio is less than or equal to 0.4, with P<P<P<Pand (P−P)+(P−P)<E the distance between Pand Prepresenting from 10% to 70% of the total thickness E of the silicon oxycarbide layer and the distance between Pand Prepresenting from 10% to 70% of the total thickness E of the silicon oxycarbide layer.
