Transparent substrate comprising a coating with mechanical strength properties

The invention relates to a transparent substrate of the type that is made from glass. The inventive substrate comprises a coating containing at least one layer C based on [nitride, carbonitride, oxynitride or oxycarbonitride] of silicon or aluminium or a mixture of the two, with a covering layer dis...

More Information
Summary:The invention relates to a transparent substrate of the type that is made from glass. The inventive substrate comprises a coating containing at least one layer C based on [nitride, carbonitride, oxynitride or oxycarbonitride] of silicon or aluminium or a mixture of the two, with a covering layer disposed thereon. The invention is characterised in that the covering layer is an oxide-based mechanical protection layer, said oxide optionally having a sub- or super-stoichiometric content of oxygen and/or optionally being nitride.
