Publication number: 20100221423Abstract: 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.Type: ApplicationFiled: May 28, 2008Publication date: September 2, 2010Inventors: Jens Dahl Jensen, Ursus Krüger, Gabriele Winkler

Patent number: 7781024Abstract: The invention relates to a method for producing ceramic layers by spraying. A cold gas spraying method is used to produce polymer ceramics from pre-ceramic polymers. According to said method, a cold gas stream, to which particles of the pre-ceramic polymers are added via a conduit, is generated by a spray gun. The energy for creating a layer on a substrate is produced by injecting a powerful kinetic energy into the cold gas stream, thus preventing or significantly restricting the thermal heating of the cold gas stream. This permits the heat-sensitive pre-ceramic polymers to be spray-applied as a coating on a substrate using a cold gas spraying method. Polymer ceramics can thus be used in an economic method for the rapid production of layers with a relatively large thickness. The invention allows for example armoured layers, thermal protection layers and other functional layers to be produced.Type: GrantFiled: June 23, 2006Date of Patent: August 24, 2010Assignee: Siemens AktiengesellschaftInventors: Ursus Krüger, Raymond Ullrich

Publication number: 20090263314Abstract: The present invention provides a method for producing catalyst for wastewater treatment, which comprising mixing polymers and additives, reacting with a titanate precursor, and then subjecting the resultant product to hydrolysis and condensation to form catalyst slurry. Due to using the titanate as a source of metal ions and the polymer compound as a dispersant and stabilizer, the aggregation between particles can be habited, and due to using additives as chelating agent and catalyst, it can improve solution stability and inhibit the oxidation of the metal, thereby facilitate the condensation and hydrolysis and shorten the reaction time. The catalyst slurry prepared by the method of the present invention exhibits excellent dispersibility to effectively contact with and decompose organics, such as those containing in wastewater and thus is suitable for wastewater treatment. In addition, the resultant catalyst slurry can be processed in the form of powder or film for using in industrial wastewater treatment.Type: ApplicationFiled: July 8, 2008Publication date: October 22, 2009Applicant: Institute of Nuclear Energy Research Atomic Energy Council, Executive YuanInventors: JEN-CHIEH CHUNG, SHU-MIN SHIH, YU-SHENG CHEN

Patent number: 7588797Abstract: A chemical composition and method for repairing a thermal barrier coating on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method repairs a thermal barrier coating on a component that has suffered localized damage to the thermal barrier coating. After cleaning the surface area of the component exposed by the localized spallation, a paste-like mixture of a ceramic composition comprising ceramic powders and nano-sized ceramic materials in a binder is applied to the surface area of the component, and is optionally smoothed using mechanical means. The composition is then allowed to dry and cure to form a dried coating having polymeric characteristics. Upon subsequent heating, the dried coating reacts to produce a glassy ceramic repair coating.Type: GrantFiled: April 7, 2004Date of Patent: September 15, 2009Assignee: General Electric CompanyInventors: Andrew Jay Skoog, Jane Ann Murphy, William Randolph Stowell, David E.

Publication number: 20090208648Abstract: A process for producing an article having modified optical, chemical, and/or physical properties is disclosed. The process includes (a) fluidizing a starting material; (b) forcing the fluidized starting material toward the article; and (c) passing the fluidized starting material through a high energy zone. The passing step can occur before the forcing step; after the forcing step but before the fluidizing material comes in contact with the surface of the article; and/or after the forcing step and after the fluidized material comes in contact with the surface of the article. The properties of the article are modified because the article has nano-scaled structures distributed on the surface of the article and/or at least partially embedded in the article.Type: ApplicationFiled: March 30, 2009Publication date: August 20, 2009Applicant: PPG INDUSTRIES OHIO, INC.Inventors: Mehran Arbab, Deirdre A.

Patent number: 7575780Abstract: A bone-growth stimulating composition for forming a resorbable implant, methods for making such a composition and a corresponding putty/paste material. In some embodiments of the invention, such a material includes a plurality of particles having a predetermined size and comprising a first calcium sulfate compound and a resorbable polymer in a predetermined weight ratio. Methods for making such a material include rotating calcium sulfate powder in a drum at a first predetermined drum speed, spraying of a resorbable polymer solution at a predetermined rate on the calcium sulfate powder over a predetermined period of time and drying the resulting particles. Such compositions allow resorption rates of the implant composition in vivo to be controlled, and my vary between eight and twenty-four weeks (for example), which can be matched to substantially correspond to a rate of bone growth in a particular application.Type: GrantFiled: March 6, 2006Date of Patent: August 18, 2009Assignee: Orthogen LLCInventors: Harold Alexander, John L.

Publication number: 20090162647Abstract: An article which is resistant to corrosion or erosion by chemically active plasmas and a method of making the article are described. The article is comprised of a metal or metal alloy substrate having on its surface a coating which is an oxide of the metal or metal alloy. The structure of the oxide coating is columnar in nature. The grain size of the crystals which make up the oxide is larger at the surface of the oxide coating than at the interface between the oxide coating and the metal or metal alloy substrate, and wherein the oxide coating is in compression at the interface between the oxide coating and the metal or metal alloy substrate. Typically the metal is selected from the group consisting of yttrium, neodymium, samarium, terbium, dysprosium, erbium, ytterbium, scandium, hafnium, niobium or combinations thereof.Type: ApplicationFiled: December 21, 2007Publication date: June 25, 2009Inventors: Jennifer Y.
