Abstract
The object of the invention is to create a hard-material coating for glass ceramics and glasses, a coating which is particularly temperature-resistant and protects the substrate from mechanically caused damage as well as chemical attack. For this purpose, a silicon nitride coating is proposed, which has a structure-free morphology in the volume.

35. A glass or glass-ceramic article coated with hard material having a glass substrate or a glass-ceramic substrate, comprising:
a silicon nitride layer is deposited on the substrate as a hard-material layer, wherein the silicon nitride layer has an x-ray amorphous morphology in the volume, and has a structure-free morphology such that it appears structure-free in an electron micrograph of the cross section with 5 kV accelerating voltage at 100,000×
