  • Publication number: 20130260173
    Abstract: Polycrystalline diamond compacts for use in artificial joints achieve reduced corrosion and improved biocompatibility through the use of solvent metal formulations containing tin and through the control of solvent metal pore size, particularly in inner layers of the compact. Solvent metal formulations containing tin have been discovered which provide sintering ability, part strength, and grind resistance comparable to levels achieved by using CoCrMo solvent metals. It has been discovered that limiting the solvent metal pore size in the diamond layers minimizes or eliminates the occurrence of micro cracks in the solvent metal and significantly reduces the corrosion of the compact as manifested by the release of heavy metal ions from the compact. Polycrystalline diamond compacts which utilize both the solvent metal formulations containing tin and the control of pore sizes achieve significantly reduced corrosion and improved biocompatibility compared to prior art polycrystalline diamond compacts.

  • Publication number: 20130115092
    Abstract: Structural repair of cracks and other defects in superalloy components, such as steam or gas turbine blades in stationary or aero gas turbines, are performed by heating the blade substrate to an isothermal hold temperature below the substrate's incipient melting point and filling the crack with molten superalloy filler material. The molten filler solidifies into a casting and bonds with the component substrate at the isothermal hold temperature. Heat treatment processes are completed, so that the former crack is filled with cast superalloy material having identical or similar structural properties as the adjoining substrate superalloy material. The casting repair method may be utilized universally for all types of superalloy component defects, including those previously repaired by cosmetic, lower strength welding or brazing methods.

  • Publication number: 20110200841
    Abstract: A new process and technical arrangement has been established for the production of grain free metal products, which can be extruded directly from the melt, by inserting a seed crystal from a seeding chamber into the opening of the extrusion jet of the melting vessel. The seed crystal will break by contact the surface tension of the liquid metal in the extrusion jet channel, which is slightly undercooled. Upon establishing contact, the temperature at the meeting point of the seed crystal and the liquid metal will be raised by RF-heating to permit the extrusion of the seed crystal backwards, ensuring that metal and seed crystal maintain contact and crystal growth will continue. It has been discovered, that single crystals with the orientation of the seed crystal will continue to grow and to establish high hardness. Speed of extrusion is exceeded to reach only grain free structure in the grown metal.

  • Patent number: 7554021
    Abstract: The present invention is directed to a composition useful for making homogeneously mineralized self assembled peptide-amphiphile nanofibers and nanofiber gels. The composition is generally a solution comprised of a positively or negatively charged peptide-amphiphile and a like signed ion from the mineral. Mixing this solution with a second solution containing a dissolved counter-ion of the mineral and/or a second oppositely charged peptide amphiphile, results in the rapid self assembly of the peptide-amphiphiles into a nanofiber gel and templated mineralization of the ions. Templated mineralization of the initially dissolved mineral cations and anions in the mixture occurs with preferential orientation of the mineral crystals along the fiber surfaces within the nanofiber gel. One advantage of the present invention is that it results in homogenous growth of the mineral throughout the nanofiber gel.

  • Patent number: 6982123
    Abstract: A nickel-base superalloy article, such as a gas turbine stationary flowpath shroud that has previously been in service, is repaired by applying a restoration coating to a surface of the article. The restoration coating is applied by providing a precursor mixture, wherein the precursor mixture has no more than about 15 weight percent chromium and no more than about 0.01 percent yttrium, and wherein the precursor mixture includes a higher-melting-point alloy component and a lower-melting-point alloy component. The precursor mixture is applied to the surface of the article, in a form such as a preform of the alloy components. The article with the precursor mixture applied to the surface thereof is heated to a sufficiently high temperature to melt the lower-melting-point alloy component, thereby forming the restoration coating on the surface of the article.

  • Patent number: 6969559
    Abstract: Magnetic field structures composed of stacked magnetic laminae that are magnetically oriented perpendicular to their planes and configured to cause a volume charge density and cancel the field effects of unwanted surface negative charges. This arrangement causes a uniform volume magnetic charge density, which results in a magnetic field normal to the laminae of the magnitude. The stacked magnetic laminae magnetic field structures cancel the field effects of the deleterious unwanted surface charges because these surface charges are so situated that their contributions to the internal magnetic field mutually cancel each other, and thus they are no longer detrimental to the magnetic field created by the volume charge density.

  • Patent number: 6884511
    Abstract: Ceramic-containing bodies can be bonded to other ceramic-containing bodies, or to metals or metal-containing bodies, by way of an aluminum-silicon brazing alloy. Such alloys feature high thermal conductivity and a melting range intermediate to Cu—Sil and Au—Si. By depositing a layer of silicon or aluminum, e.g., by vapor deposition, onto a surface of the ceramic-containing body, the formation of deleterious intermetallic phases at the brazing interface is avoided. This technique is particularly useful for joining reaction-bonded silicon carbide (RBSC) composite bodies, and particularly such composite bodies that contain appreciable amounts of aluminum as a metallurgical modification of the residual silicon phase. When the RBSC body contains minor amounts of the aluminum alloying constituent, or none, the metallization layer is not required. The resulting bonded structures have utility as mirrors, as packaging for electronics, and in semiconductor lithography equipment, e.g.

    Abstract: A magnetic recording medium was a high normalized coercive force and superior thermal stability. The magnetic recording medium comprises a non-magnetic base material, and a ferromagnetic metal layer of cobalt based alloy formed on top of this base material with a metal underlayer disposed therebetween, and displays a coercive force Hc of at least 2000 (Oe) and an anisotropic magnetic field Hkgrain of at least 10,000 (Oe). Furthermore, magnetic recording media in which the aforementioned metal underlayer and/or the ferromagnetic metal layer are fabricated in a film fabrication chamber with an ultimate vacuum at the 10?9 Torr level are preferred. A magnetic recording medium according to the present invention can be ideally applied to hard disks, floppy disks, and magnetic tapes and the like.

  • Patent number: 6838189
    Abstract: Magnetic recording media exhibiting high SNR and high thermal stability are produced by sputter depositing a magnetic alloy overlying a non-magnetic substrate, e.g., on an underlayer, heating to eliminate thermally unstable small grains thereby increasing the average grain size of the magnetic alloy layer but narrowing the grain size distribution, depositing a layer comprising a non-ferromagnetic element, and then heating to diffuse the non-ferromagnetic element into the grain boundaries of the heat treated magnetic alloy layer. Embodiments include heating to diffuse the non-ferromagnetic element leaving a layer comprising the non-ferromagnetic element, at a thickness up to about 3?, on the magnetic alloy layer, with the amount of the non-ferromagnetic element diffused into the grain boundaries of the magnetic alloy layer gradually decreasing from the upper surface of the magnetic alloy layer toward the underlayer.
