The invention relates to a device for the qualitative and/or quantitative determination of at least one component of a chemically reducible gas mixture, an exhaust gas catalytic converter utilizing such a device, a vehicle including such a catalytic converter, a process for preparing such a device, a process for monitoring the NOemissions of a vehicle, and the use of such a device.

Sensor-integrated device

A heat-insulating layer system for a metallic structural component, especially for a structural component of a gas turbine such as an aircraft engine, includes an adhesion promoting layer (), an inner contact layer (), and an outer cover layer () , whereby the adhesion promoting layer (). is disposed on a surface () of the gas turbine structural component (). The inner contact layer () is formed of a zirconium oxide partially stabilized with yttrium or yttrium oxide, and the outer cover layer () is formed of a material that consists of at least one component with at least one phase, which stoichiometrically comprises 1 to 80 Mol-% MxO, 0.5 to 80 Mol-% MyO and AlOas a remainder with incidental impurities, wherein Mx is selected from the elements chromium and barium or mixtures thereof, and wherein My is selected from the alkaline earth metals, the transition metals and the rare earths or mixtures thereof.

Heat-insulating layer system

The subject matter of the invention is a thermal-insulating material having an essentially magnetoplumbitic crystal structure, a metal substrate having a adhesive layer and a thermal-insulating layer made of the thermal-insulating material on its surface, and a process for coating metal substrates with the thermal-insulating material.

Thermal-insulating material having an essentially magnetoplumbitic crystal structure

Thermal-insulating material provided on a metal substrate by means of an EB-PVD process includes a metal having a substantially magnetoplumbitic crystal structure and having a chemical composition according to general formula: LnMQA1O. The thermally-insulated metal substrate may advantageously include an adhesive layer provided between the surface of the metal substrate and the thermal-insulating layer. The process for producing the thermal-insulated metal substrate includes applying the thermal-insulating material onto a surface of the metal substrate employing an EB-PVD process.

The present invention relates to a process for coating high-temperature-resistant fibrous materials with metal aluminates. The disclosed process includes immersing the starting fibrous material in a sol derived from at least two compounds: a compound of cerium or lanthanum and a compound of aluminum, to deposit a coating of metal aluminate on the fibrous material. The compounds of cerium, lanthanum and aluminum are selected from nitrates, acetates, oxalates and acetylacetonates. After the immersion, the fibrous material is removed from the sol after it is wetted, dried at temperatures of less than 400 degrees C. for at least 1 hour under pressure of less than or equal to 5 mbar and the fibrous material is introduced into a desired matrix at a temperature of more than 600 degrees C.
