Abstract: A method applies a titanium aluminide alloy on a substrate. The titanium aluminide alloy has a gamma phase proportion of at least 50% based on an overall composition of the titanium aluminide. The method includes: pretreating a surface of the substrate; heat treating titanium aluminide powder particles at a temperature range of 600° C. to 1000° C. to increase the proportion of the gamma phase; cold spraying the heat-treated powder particles onto the substrate or a part of the substrate to form a layer of titanium aluminide; and thermally post-treating the layer of titanium aluminide applied to the substrate.

Abstract: A method for coating a substrate having a cavity structure, in particular a cooling structure, inside the substrate, wherein the cavity structure includes openings in the surface of the substrate. At least one bonding layer, in particular a diffusion layer, or at least one metallic layer is applied onto the substrate, in particular onto the surface of the substrate, and subsequently at least one thermal protection layer is applied onto the at least one diffusion layer by using a plasma spray physical vapour deposition (PS-PVD) method, a hollow cathode sputtering method or a suspension plasma spray (SPS) method.

Abstract: A method for producing a sensor on the surface of a functional layer, in which suitable sensor material in the form of powder or a wire is melted in a laser beam by way of a method similar to laser cladding and subsequently is applied to the surface of the functional layer. There is provided a considerably improved method for producing sensors, and in particular in-situ sensors, wherein the sensors can also be deposited onto a functional layer that, in part, is very coarse, without having to employ complex masks, as has previously been customary. The ease of adapting the method parameters ensures broad use both with respect to the sensor to be produced and the functional layer to be detected. The sensors thus produced are used, in particular, to detect components that are subject to high temperatures or the functional layers thereof. The sensors that can be produced in accordance with the invention include, in particular, temperature, pressure or voltage sensors, as well as acceleration sensors.

Abstract: To apply a thermal barrier coating (10), a plasma jet (5) is generated by a plasma torch in a work chamber (2) and is directed to the surface of a substrate (3) introduced into the work chamber, and a ceramic coating material is applied to the substrate surface by means of PS-PVD, wherein the coating material is injected into the plasma jet as a powder and is partly or completely vaporized there. On applying the thermal barrier coating, in a first workstep the feed rate of the injected powder is set so that a large part of the injected powder vaporizes, wherein the coating material condenses from the vapor phase on the substrate surface and forms mixed phases with the material of the substrate surface.

Abstract: Provided is a method for internally coating the pores of a porous functional coating made of a base material with a hardening material that reduces the diffusion of the base material and/or the reactivity of the base material with the environment thereof. The hardening material is deposited from the gas phase onto the interior surfaces of the pores. It was recognized that by depositing hardening material from the gas phase, it can be introduced much deeper into the pore system of the functional coating than had been possible according to the prior art. This applies in particular when the hardening material is not itself introduced into the pore s stem, but rather one or two precursors thereof, and from said precursors the actual hardening material forms at the internal surfaces of the pores.

Abstract: Apparatus for cooling a fluid. The apparatus has an ice storage reservoir (5) and tubes (12, 9) by which a cooling fluid or a cooled fluid may pass through the reservoir (5), where the fluids may exchange heat with the ice. At least one and preferably both of the fluids are air. The fluids may circulate in the storage reservoir (5) either independently or alternately, in which case the same fluid can alternately function as the cooling fluid and the cooled fluid. The apparatus is consequently simplified and therefore more reliable.

Abstract: An air-processing installation designed to ventilate and air-condition seal rooms, as well as an air-processing module designed for the making of an installation of this type are disclosed. With each room to be air-conditioned, there is associated a structurally and functionally independent air-processing module housed in an engine room common to the different air-processing modules and remote controlled, independently of the other air-processing modules, from the associated room. Preferably, the modules are suspended in a mutually juxtaposed state in the engine room. An installation of this type reconciles requirements of hygiene and comfort with easy maintenance while at the same time, occupying the minimum amount of space.
