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.

Inner coating of lamp vessels, such as discharge vessels of gas discharge lamps

A reactor for simultaneous coating of eyeglasses on both sides thereof. Two partial devices are provided, each with a microwave energy waveguide, a gas supply and an apparatus for evacuating the coating chamber where the first and second devices can be moved relative to each other to open and close the coating chamber. The coating chamber itself is removable from the device and includes two gas supply connections and two connections for evacuating the coating chamber as well as microwave windows for coupling in microwave energy.

Volume-optimized reactor for simultaneously coating eyeglasses on both sides

An apparatus for coating objects having a single microwave source, two or more coating chambers, and an impedance structure or a waveguide structure. The coating chambers are connected to the single microwave source. The impedance structure or waveguide structure divides the microwave energy in order to generate plasmas in the coating chambers.

Device for the coating of objects

A method for producing optical functional coatings comprising niobium, tantalum, titanium or aluminum by supplying a precursor gas of low vapor pressure in a CVD coating system. A precursor selected from the group consisting of Nb, Ta, Ti, and Al compounds having a vapor pressure is maintained within a first supply container at a first temperature Tand a first pressure p. Precursor vapor of the precursor is supplied from the first supply container to an intermediate storage device through a first gas line which fluidly communicates the first supply container and the intermediate storage device. A carrier gas or reaction gas is supplied to the first gas line such that a mixture of the precursor with the carrier gas or the reaction gas is provided. The mixture is maintained in the intermediate storage device at a constant second pressure plower than the first pressure pand at a second temperature Tlower than the first temperature T, and the mixture is supplied from the intermediate storage device through a second gas line.

Gas supply method in a CVD coating system for precursors with a low vapor pressure

The invention relates to a coated object in which coatings remain of a constant and unchanged high quality despite operating temperatures of more than 350&#xb0; C. This is achieved with interlayers which deliberately interrupt and thereby stabilize the morphology of the coating.

Coated object

The invention relates to a process for producing an object which has optical layers. According to the invention such a process comprises the following process steps: To a substrate of plastic material several optical layers are applied; the optical layers are applied by means of a chemical plasma-impulse vaporization (PICVC).

Object which has optical layers

An apparatus supplies CVD coating devices with coating gas and includes an intermediate reservoir for accommodation of the gaseous coating material arranged between a storage tank and a coating device. The volume of the reservoir is set to a predetermined, maximum pressure change in the intermediate reservoir upon withdrawal of the mass of gas required for a coating step. The intermediate reservoir can be connected to a gas recovery station.
