20080277618 | Heat-Insulating Material, Production Method and Use Thereof - The invention relates to a heat-insulating material, which is phase-stable particularly for high temperatures above 1150° C., especially above 1200° C., and which has a very good long-time stability. The heat-insulating material can exist in a number of phases of which at least one has the magnetoplumbite structure and stoichiometrically contains 0.1 to 10 mol % M1 | 11-13-2008 |
20090098390 | HEAT-INSULATING LAYER MADE OF COMPLEX PEROVSKITE - A heat-insulating layer has a melting point above 2500° C., a thermal expansion coefficient in excess of 8×10 | 04-16-2009 |
20090110904 | Sandwich Thermal Insulation Layer System and Method for Production - A method produces thermal barrier coatings that adhere to components even at high temperatures and temperatures that change frequently. A gas-tight glass-metal composite coating is applied to the component and annealed. The corroded part of the gas-tight coating is then removed, and a second, porous coating is applied. The second coating can comprise a ceramic, in particular yttrium-stabilized zirconium oxide. A thermal barrier coating is provided that is a composite made of a gas-tight glass-metal composite coating and another porous coating disposed thereover. Because the boundary volume of the composite coating is partly crystallized to the other coating, superior adhesion within the composite is achieved. Thus, it is in particular possible to produce a composite made of silicate glass-metal composite coatings and yttrium-stabilized zirconium oxide that are temperature-stable for extended periods of time. Such a composite is particularly advantageous for use as a thermal barrier coating because it combines good protection against oxidation with low heat conductivity and susceptibility to aging. | 04-30-2009 |
20110244216 | THERMAL BARRIER COATING SYSTEM AND METHOD FOR THE PRODUCTION THEREOF - Disclosed is a method for producing a coating system on a component, wherein at least one coating is deposited on the component by way of atmospheric plasma spraying (APS) and at least one further coating is deposited by way of suspension plasma spraying (SPS). The coatings are particularly advantageously deposited in the sequence of APS+SPS or APS+SPS+APS or APS+SPS+erosion coating. These sequences of coatings applied in this way usually have an effect providing a first porous coating and a second porous coating disposed thereon, wherein the porosity of the second coating is greater than that of the first coating, and wherein the reflectivity is greater than that of the first coating. The increased reflectivity of the coating, particularly in the visible (VIS) and the near infrared (NIR) wavelength ranges, advantageously causes a lower thermal load for the substrate material because a smaller proportion of thermal radiation penetrates the ceramic thermal barrier coating, resulting in lower heating of the substrate (component). | 10-06-2011 |
20120190118 | COMPONENT HAVING A PROTECTIVE LAYER THAT CAN BE MONITORED MAGNETICALLY AND METHOD FOR OPERATING A COMPONENT - A component for high-temperature use comprises a metallic base material and a non-ferromagnetic protective layer arranged thereon, which is able to form a protective oxide layer on the component surface at temperatures between 600° C. and 1100° C. A sensor material is introduced into the protective layer, wherein, in the stated temperature range, the local magnetism, notably ferromagnetism or ferrimagnetism, at the site of the sensor material is dependent on the local concentration and/or composition of the material of the protective layer in the immediate vicinity of the sensor material and/or on the cumulative temperature-time curve at the site of the sensor material. The component can be examined non-destructively, from the outside, for the local magnetism in the protective layer, which is typically between 100 μm and 500 μm thick. | 07-26-2012 |
20130196141 | PROCESS FOR INTERNALLY COATING FUNCTIONAL LAYERS WITH A THROUGH-HARDENED MATERIAL - 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. | 08-01-2013 |
20130220126 | PLASMA SPRAY METHOD FOR THE MANUFACTURING OF AN ION CONDUCTING MEMBRANE AND AN ION CONDUCTING MEMBRANE - A plasma spray method for the manufacture of an ion conducting membrane, in particular of a hydrogen ion conducting membrane or of an oxygen ion conducting membrane is suggested. In which method the membrane is deposited as a layer ( | 08-29-2013 |
20130224393 | Plasma Spray Method - The invention relates to a plasma spray method which can serve as a starting point for a manufacture of metal nanopowder, nitride nanopowder or carbide nanopowder or metal films, nitride films or carbide films. To achieve an inexpensive manufacture of the nanopowder or of the film, in the plasma spray in accordance with the invention a starting material (P) which contains a metal or silicon oxide is introduced into a plasma jet ( | 08-29-2013 |
