20080277288 | Method For Removing A Coating From A Component - Method for removing coatings which have been applied to components such as turbine blades. After the end of the product life cycle of the turbine blades has been reached, these coatings can be removed to reuse the turbine blades after recoating. The coating, containing in particular chromium oxide compounds is removed via a stripping bath by adding alkanolamine compounds or salts containing such compounds as the inhibitor. These compounds advantageously prevent new chromium oxide compounds from being produced during the stripping of the turbine blades or the chromium oxide compounds present in the coating are removed effectively, so that the chromium oxide compounds cannot have an adverse influence on the removal rate of the stripping process. Advantageously reduced treatment times can thereby be achieved for the stripping process. By adding 2% triethanolamine, the treatment time in hydrochloric acid for example can be reduced to below one hour. | 11-13-2008 |
20090005233 | Component with a ceramic coating, into which particles are embedded, and method for producing said component - The subject matter of the invention is a component which is provided with a ceramic coating forming the surface. Inventively there is provision at least in a cover layer of the coating for nanoparticles made from a colorant (CrCoAl or a spinel-type oxide) and aluminum oxide nanoparticles. This combination of nanoparticles in the coating advantageously results in a resistance to high temperatures of the coloring of the surface of up to 1000° C. not previously known. This allows even components under great stress, such as for example compressor or turbine blades of a gas turbine, to be provided with temperature-resistant coloring. This can then be used for an optical inspection for example. Protection is also claimed for a method for creating the inventive coating | 01-01-2009 |

20100221423 | METHOD FOR CREATING A DRY LUBRICANT LAYER - In a method for creating a dry lubricant layer, the layer is formed by a coating material which is first applied to a substrate, on which the dry lubricant layer is to be produced. The coating material contains a solvent such as ethanethiol and the precursors of a metal sulphide, in particular a metaloxysulphide, such as a molybdenum salt of dithiocarboxylic acid. Once the coating material has been applied to the substrate, the material is subjected to thermal treatment, whereby the solvent evaporates and the precursors of the metal sulphide react with one another to form the dry lubricant layer. This advantageously permits the creation of dry lubricant layers containing a high fraction of metal sulphide, giving the layers improved sliding friction characteristics. Another advantage is that the oxysulphide layers that have been formed are also particularly stable in relation to an oxidation. | 09-02-2010 |
20110033692 | COMPOSITE MATERIAL COMPOSED OF A METAL MATRIX IN WHICH CNT FILAMENTS ARE DISTRIBUTED, AND METHOD FOR THE PRODUCTION OF SUCH A COMPOSITE MATERIAL - A composite material is composed of a metal matrix in which CNT filaments are distributed. The CNT filaments are intertwined, interwoven, or tied together, and the matrix is cold-worked. The matrix material is thereby filled with a higher percentage of CNT filaments than when dispersed CNT are electrodeposited. In a method for producing such a composite material, suitable semifinished products such as knitted fabrics, woven fabrics, nets, fleeces, or papers made of CNT filaments are coated (preferably electroplated) with the metal matrix. | 02-10-2011 |

20120128872 | METHOD FOR FABRICATING A LAYER WITH ABSORBING PARTICLES FOR AN ENERGY RADIATION - A ceramic layer is fabricated on a substrate by coating the substrate with a material containing chemical precursors of a ceramic. The precursors are transformed by a heat treatment into the ceramic to be fabricated. Different methods for heat insertion may be used for individual layers by absorbing particles, which are utilized in different concentrations or different chemical compositions. A targeted heat insertion even in lower layer regions, for example, by microwave animation, or ultraviolet or infrared light insertion is therefore possible. Beneficially, as a result, comparatively thick layers in particular can be fabricated by a single heat treatment layer. | 05-24-2012 |
20120269982 | METHOD FOR ELECTROCHEMICAL COATING - In a method for coating a work piece, a layer is electrochemically produced from a first material. In order to generate an inhomogeneous expansion behavior of the layer, a thermal spraying, in particular a cold gas spraying, achieves that specific zones are created in the layer from a material having a different thermal expansion behavior. These zones expand more laterally than in the direction of the layer thickness so that directed internal stresses occur in the layer upon heating or cooling of the component, which can be specifically utilized depending on the design conditions of the component. | 10-25-2012 |
20130187099 | ELECTRICALLY INSULATING NANOCOMPOSITE HAVING SEMICONDUCTING OR NONCONDUCTIVE NANOPARTICLES, USE OF THIS NANOCOMPOSITE AND PROCESS FOR PRODUCING IT - A cellulose material contains cellulose fibers having an impregnation. Accordingly, the impregnation is made of nanoparticles, in particular BNNT, containing a shell of polymers, in particular PEDOT:PSS. The impregnation forms a type of network that can reduce the specific resistance of the cellulose material due to the electrical conductivity of the network. The cellulose material can thereby be advantageously adapted to corresponding applications with respect to the electrical properties thereof. The cellulose material can thus also be used to electrically insulate transformers, wherein the cellulose material is thereby saturated with transformer oil and an adaptation of the specific resistance of the cellulose material to the specific resistance of the oil leads to improved dielectric strength of the transformer insulation. A method for producing the cellulose material described above contains a suitable impregnation step for the cellulose material. | 07-25-2013 |
