A cathode-electrolyte-anode unit for an electrochemical functional device, in particular a high-temperature fuel cell. The unit has a multi-layer solid-state electrolyte arranged between a porous anode and a porous cathode. The solid-state electrolyte is produced by a vapor deposition process and has a sandwich-type structure consisting of at least one first layer with a lower oxygen content, and at least one second layer with a higher oxygen content. The individual layers have substantially the same composition, with the exception of oxygen.

An internal combustion engine is presented having at least one combustion chamber, wherein a surface of at least one component of the combustion chamber and/or of an internal-combustion-engine component which is close to the combustion chamber and carries the exhaust gas stream is at least partially coated with a catalytic coating. The surface will come into contact with an air-fuel mixture or with an exhaust gas stream.

The invention relates to a grain-oriented magnetic steel sheet including an electrically insulating coating made of an amorphous carbon-hydrogen network, which is applied after final annealing in order to ensure electrical insulation of the individual layers of the sheet. The grain-oriented magnetic steel sheet including the electrically insulating coating made of an amorphous carbon-hydrogen network can be used in transformers.

A method for surface treatment of at least one electrically conducting substrate or a substrate that has been coated so as to be conducting () by means of a gas placed in the region of an electric discharge (). The discharge region is restricted by at least two essentially opposite sides of the substrate surface to be treated (). This process is especially suitable for treating band-shaped and continuously supplied substrates.

Method and device for surface-treating substrates

The invention concerns a device and a method for coating and/or surface modification of objects in a vacuum using a plasma, where there is the possibility of coating or modifying variform objects on all sides without a large expense for plant or process engineering being necessary. In accordance with the invention, a box structure () of an electrically conductive material that forms a vacuum chamber or can be inserted into a vacuum chamber is used. Objects () can be introduced into the box structure to at least one closable opening () at a distance from the inner wall. In addition, there are at least one opening () for supply and at least one opening () for removal of the operating gas as well as one opening (') for introduction of energy for generation of a glow discharge and the box structure () has a potential that is electrically negative with respect to the plasma generated by the glow discharge.

The invention relates to a device for coating an object at a high temperature by means of cathode sputtering, having a vacuum chamber and a sputter source, the sputter source having a sputtering cathode. Inside the vacuum chamber is arranged an inner chamber formed from a heat-resistant material, which completely surrounds the sputtering cathode and the object to be coated, at a small spacing, and which has at least one opening to let a gas in and at least one opening to let a gas out.

Device and method for coating objects at a high temperature

The invention relates to a method and device for improving the surface of a substrate. Plasma is produced by a luminous discharge, close to the substrate to be treated, using a hollow cathode and an anode assigned thereto. A reactive gas located in the area of the luminous discharge is activated, causing a change to occur on the surface of substrate to provide the desired improvement. The hollow cathode is brought to a self-cleansing temperature and maintained at said temperature, whereby the parasitic deposits caused by the reactive gas are removed and/or converted. The self-cleansing temperature is stabilized by taking into account the following factors: the heating of the hollow cathode by the luminous discharge, thermal conduction carried out by the reactive gas and radiation in the direction of a cooled anode arranged at a small distance from the hollow cathode.

Method and device for improving surfaces

The invention relates to a component having a substrate and a ceramic heat-insulating layer which is arranged thereon. This heat-insulating layer has a columnar structure having ceramic stems which are essentially oriented mainly normal to the surface of the substrate and have a respective stem diameter of less than 2.5 &mgr;m. The invention also relates to a coating apparatus for producing a heat-insulating layer on a substrate and to a method of coating a substrate in the manner of a reactive gas-flow sputtering method.
