  • Patent number: 9731377
    Abstract: A method of bonding a first article to a second article, each article having a respective bond surface. The method comprises interposing a porous interlayer region between the bond surfaces of the first and second articles and subsequently using electrical resistance heating to locally heat the interlayer region under contact pressure to a bonding temperature below the melting temperature of the interlayer and the first and second articles to thereby bond the interlayer to the first and second articles to form a bonded article. The interlayer has a porosity of between approximately 10% and 30%.

  • Publication number: 20130177740
    Abstract: A powder-based material system having an intrinsic and stable degree of porosity provided by hollow ceramic spheres (26) in a fully dense matrix (27). A substrate (22) is formed from a metal powder (70), and may be partially sintered (60). A layer (24) of ceramic powder is arranged on the substrate including the pre-sintered hollow ceramic spheres plus a proportion of nano-sized ceramic particles effective to reduce the layer sintering temperature and to increase the sintering shrinkage of the layer to approximate that of the metal substrate during subsequent co-sintering. The substrate and layer are then co-sintered (61), such as with spark plasma sintering (32, 34, 36), at a temperature and for a duration to fully densify the ceramic powder matrix around the hollow spheres, thereby producing a metal/ceramic material system with low interface stress and with stable porosity during operational temperatures in a gas turbine engine.

  • Patent number: 8114474
    Abstract: A metallic glass particle layer is applied to aluminum alloy armor and friction stir mixed into the surface in order to embed the material into the armor and to take advantage of its exceptional hardness. An advantage of the invention is that the hard material is an integral part of the armor, included within the body of the armor plate and not merely a surface coating. The advantage of the friction stir process is that it generates relatively low levels of heat and magnetic measurements show that the amorphous phase condition of the metallic glass is not deteriorated. The armor may be tempered to improve properties.

  • Patent number: 6889529
    Abstract: A method for producing an optical fiber preform is provided in which the variation of the outer diameter in the longitudinal direction is minimized and a target quantity of glass is accumulated as a whole. Based on a predetermined relationship between three variables: the outer diameter of a starting rod being a first variable, the outer diameter of an optical fiber preform a second variable, and the timing for ending the glass particles depositing process a third variable, the starting rod and burners are subjected to relative reciprocating movement so as to deposit glass particles on the starting rod until the timing for ending the depositing process, and then the resulting deposit body is vitrified. The third variable may be the traverse velocity, the glass particles deposition time, or the weight of a soot glass deposit body.

  • Patent number: 6756073
    Abstract: A method is provided for applying metallic or metal-ceramic coatings to a product surface, particularly during the manufacture and repair of pressurized articles and products which require increased corrosion resistance, heat resistance and other qualities. Compressed air is preliminary heated to a temperature of from 400 to 700° C., forming a high-velocity air flow in a supersonic nozzle. A powder material, which is a mechanical mixture of ceramic and metal powders, is accelerating by the flow and is applied to a product surface. The metal powder is a powder mixture of at least two metals, one of which is zinc powder in an amount of from 20 to 60% of the metal powder total weight. The presence of zinc in the powder material and the heating of the compressed air to 400 to 700° C. assures high-efficiency production of coatings having low gas-permeability and high coating-to-substrate bond strength.

  • Patent number: 6548162
    Abstract: Sanitary wares having a controlled surface are disclosed which are less likely to be stained or soiled and/or possess excellent gloss. The first sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface glaze layer has a center line average roughness Ra of less than 0.07 &mgr;m. This sanitary ware is advantageous in that stains or soils are much less likely to be adhered to the surface thereof and, even when adhered to the surface thereof, can be removed by a weak water stream. The second sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface glaze layer has a kurtosis Rku of less than 2.70. This sanitary ware advantageously possesses excellent surface gloss.

    Abstract: The invention relates to a method for producing a monolithic, porous, ceramic shaped body and to the shaped bodies produced according to this method. Said shaped body is used predominantly as a support material for porous, inorganic and/or organic membranes for the flow filtration of liquids and gases. The aim of the invention is to provide a method for producing a shaped body consisting substantially of TiO2 with an open porosity >10%, an average pore size of between 1 and 50 &mgr;m and a mechanical stability >20 N/mm2. To achieve this, a first TiO2powder fraction is pre-sintered at temperatures >1200° C.

  • Publication number: 20020114883
    Abstract: A process for forming a retroreflective layer on a powder coated substrate is provided. The substrate is powder coated and the powder coating is subsequently partially cured. Reflective elements are then partially embedded in the semi-cured powder. The powder is then fully cured to permanently bond the reflective elements with the powder coating. The resultant retroreflective assembly can be used in any application requiring high detectability in poor visibility conditions, such as road signs and the like.

  • Patent number: 6413589
    Abstract: A method of coating a ceramic and bonding ceramic onto a substrate for practical uses over 630° C. includes forming a brazed bonding layer at a contact area between the ceramic and the substrate by a fluidic reaction and causing the bonding layer to wet both the ceramic and substrate with a wetting angle of 0-5° to thereby coat and bond the ceramic onto bond the substrate over the entire contact area with a continuous, essentially 100% dense bonding layer. The bonding layer is so free of bonding defects that the resulting bonded product can withstand repeated thermal shocks by quenching in 0° ice water from a temperature in the range of 630-980° C.
