In order to provide a thermostable and highly effective barrier coating on a substrate, and to protect the substrate against the effect of harmful gas components even at high temperatures, the invention provides a coated substrate comprising a barrier coating having a multiplicity of consecutive individual layers respectively of a kind differing from or similar to a neighboring individual layer, the individual layers exhibiting a layer thickness of respectively at most 50 nanometers.

Fine laminar barrier protective layer

The invention relates to a discharge vessel of a quartz glass for discharge lamps with a diffusion barrier inner layer of silicon oxide, which as a single layer is applied and/or is generated on the inner surface as well as to a method for generating and/or applying such a diffusion barrier inner layer and to the use of such a discharge vessel.
