  • Publication number: 20140329021
    Abstract: Producing high temperature coatings on ceramics using a high enthalpy air plasma spray torch and supplying in at least 3 passes to deposit the coating is advantageous for spraying high temperature ceramics while avoiding formation of undesirable phases, if the stand off distance is chosen such that a width of a bead produced from a single spray pass on the substrate at ˜800° C. is less than 70% of a diameter of a plume of the torch at the stand off, and neither assisted heating, nor forced cooling, nor subsequent heat treatment is used. The rapid cooling endemic to thermal spray that leads to amorphous, metastable and other undesirable phases of alkaline earth aluminosilicate (e.g., barium-strontium aluminosilicate (BSAS)), rare earth silicates (RESs), mullite, etc. can be mitigated sufficiently by the close stand off and high enthalpy torch to provide highly crystalline and stable phase coatings.

Because the plasma spray coating used to coat the pure metallic material on the zirconium alloy does not require vacuum equipment and also is not limited due to the shape of the coated product, this is particularly useful when evenly treating the surface of the component such as 4 m-long tube or spacer grip arrangement which is very complicated in shape. Furthermore, because the coated zirconium alloy confers excellent resistance to oxidation and corrosion under emergency such as accident as well as normal service condition, both the economic and safety aspects of nuclear fuel are improved.

  • Patent number: 8414970
    Abstract: Certain example embodiments relate to a method of forming a coating on a glass substrate using combustion deposition. A glass substrate having at least one surface to be coated is provided. An organosiloxane inclusive precursor having a ring- or cage-like structure to be combusted is introduced. Using at least one flame, at least a portion of the precursor is combusted to form a combusted material, the combusted material including non-vaporized material. The glass substrate is provided in an area so that the glass substrate is heated sufficiently to allow the combusted material to form the coating, directly or indirectly, on the glass substrate. In certain example embodiments, the precursor is a cyclic siloxane based and/or polyhedral silsesquioxane (POSS) based precursor, which advantageously may affect the coating's transmission and/or reflection properties compared to conventionally used silicon precursors.

  • Patent number: 8377831
    Abstract: A method for size selection of nanostructures comprising utilizing a gas-expanded liquids (GEL) and controlled pressure to precipitate desired size populations of nanostructures, e.g., monodisperse. The GEL can comprise CO2 antisolvent and an organic solvent. The method can be carried out in an apparatus comprising a first open vessel configured to allow movement of a liquid/particle solution to specific desired locations within the vessel, a second pressure vessel, a location controller for controlling location of the particles and solution within the first vessel, a inlet for addition of antisolvent to the first vessel, and a device for measuring the amount of antisolvent added. Also disclosed is a method for forming nanoparticle thin films comprising utilizing a GEL containing a substrate, pressurizing the solution to precipitate and deposit nanoparticles onto the substrate, removing the solvent thereby leaving a thin nanoparticle film, removing the solvent and antisolvent, and drying the film.

  • Patent number: 8359884
    Abstract: A glass sheet is formed using a roll-to-roll glass soot deposition and sintering process. The glass sheet formation involves forming a first glass soot layer on a deposition surface of a soot-receiving device, removing the first glass soot layer from the deposition surface, and forming a second glass soot layer on the unsupported first glass soot layer. The resulting composite glass soot sheet is heated to form a sintered glass sheet. The glass sheet can be a substantially homogeneous glass sheet or a composite glass sheet having layer-specific attributes.

  • Publication number: 20120321812
    Abstract: Embodiments of the invention provide a thermal spray method of forming a protective and porous coating over desired surfaces. Further, embodiments provide a thermal arc spray method, such as twin wire arc spray, to coat the surfaces. The invention may refer to using Aluminium and Silicon alloy in a twin wire arc spray method, to create sacrificial and protective coatings on the surfaces, such as substrates and machine parts. Machine parts may be, for example, of sputtering system. The method may utilize a predefined range of Silicon to be alloyed with Aluminium to improve the physical properties of the Aluminium, and further avoid damages to the coated surface, such as de-lamination and flaking of the coatings and coated surfaces. Additionally, generation of defects during a sputtering process may be efficiently reduced.
