A method for production of a substrate having a patterned optical coating on a curved surface is provided. The method includes applying a masking to a sub-area of the curved surface applying an optical coating using a vacuum deposition method, and removing the masking. A coated substrate, which can be produced in particular by the method described above, is also provided. The coated substrate includes a curved surface that is provided with at least one patterned optical coating. The at least one patterned optical coating is provided on at least one sub-area of the curved surface and is missing on at least one adjacent sub-area.

Coated substrate with a curved surface, and a method for production of a coated substrate such as this

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

In the case of CVD methods, comprising PECVD and PICVD methods, the aim of the invention is to improve the impurity-free and, as far as possible, temporally and quantitatively precise feeding of process gases for the targeted layer systems. To this end, the invention provides a coating system and a method for coating articles with alternating layers, in the case of which process gases are introduced in an alternating fashion into a gas mixing point and mixed with a further gas and led to the reaction chamber, in which the deposition is carried out by producing a plasma.

Coating system and method for coating, as well as coated articles

A method and apparatus for coating substrates by means of plasma enhanced vapor deposition are provided, in which at least part of the surroundings of the substrate surface of a substrate to be coated is evacuated and a process gas with a starting substance for the coating is admitted, wherein the coating is deposited by a plasma being ignited by radiating in electromagnetic energy in the surroundings of the substrate surface filled with the process gas. The electromagnetic energy is radiated in by a multiplicity of pulse sequences, preferably microwave or radiofrequency pulses, with a multiplicity of pulses spaced apart temporally by first intermissions, wherein the electromagnetic energy radiated in is turned off in the intermissions, and wherein the intermissions between the pulse sequences are at least a factor of 3, preferably at least a factor of 5, longer than the first intermissions between the pulses within a pulse sequence.

Method and apparatus for plasma enhanced chemical vapor deposition

The invention relates to layer systems having at least one layer comprising titanium aluminum oxide. The layer comprising titanium aluminum oxide may be either a functional layer&#x2014;with or without interruption by an intermediate layer which is optically inactive&#x2014;or a functional layer formed from a metal oxide which is interrupted by an intermediate layer comprising titanium aluminum oxide. The layer systems are structurally and thermally stable at operating temperatures of over 600&#xb0; C. The layer systems may either comprise only one functional layer or may be a multilayer system, preferably an alternating layer system composed of functional layers with high and low refractive indices.

Layer system

A method of producing substrates with functional layers which have high optical properties and/or a high surface smoothness, in particular a low turbidity and significantly lower roughness, is provided. The method includes a sputtering process for coating a substrate with at least one functional layer, the sputtering process being interrupted at least once by the application of an intermediate layer with a thickness of less than 20 nm.

Process for producing layers and layer systems, and coated substrate

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

A process for producing an object which has optical layers comprising the steps of applying optical layers to a substrate of plastic material wherein the optical layers are applied by means of a chemical plasma-impulse vaporization process (PICVD).
