  • Patent number: 8449991
    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.

In this manner, because the final mechanical tolerance is controlled by machining instead of part assembling, extremely high alignment accuracy is obtained. The final part provides field shielding as provided by the nickel alloy shell, low stray field provided by the non-magnetic Hastelloy, good vacuum performance, and tight mechanical tolerance control. Also, because Hastelloy has the advantage of a low oxidation rate in comparison to stainless steel and titanium, there is less contamination buildup due to conditions such as electron beam bombardment.

  • Patent number: 7762448
    Abstract: A composite body which can withstand high thermal stresses is formed by high-temperature soldering at least a part of a high-temperature-resistant, metallic or nonmetallic component and at least a part of a high-temperature-resistant, nonmetallic component. Prior to soldering, a metallic barrier layer, which is impervious to the solder melt, of one or more elements selected from the group consisting of V, Nb, Ta, Cr, Mo, W, Ti, Zr, Hf and alloys thereof, is deposited on that surface of each nonmetallic component which is to be soldered. Solder material, barrier layer and soldering conditions are adapted to one another in such a manner that during the soldering operation the metallic barrier layer remains at least partially in the solid state, so that after the soldering operation it is still present in a thickness of at least 10 ?m at least over the majority of the soldering surface.

  • Publication number: 20100117764
    Abstract: The selective growth of vertically aligned, highly dense carbon nanotube (CNT) arrays using a thermal catalytic chemical vapor deposition (CCVD) method via selection of the supporting layer where the thin catalyst layer is deposited on. A thin iron (Fe) catalyst deposited on a supporting layer of tantalum (Ta) yielded CCVD growth of the vertical dense CNT arrays. Cross-sectional transmission electron microscopy revealed a Vollmer-Weber mode of Fe island growth on Ta, with a small contact angle of the islands controlled by the relative surface energies of the supporting layer, the catalyst and their interface. The as-formed Fe island morphology promoted surface diffusion of carbon atoms seeding the growth of the CNTs from the catalyst surface.

  • Publication number: 20090286104
    Abstract: Multiple layers of nickel phosphorous coatings are formed by electroless plating onto a base metal substrate such as a turbine component. In one embodiment, a first nickel layer metallurgical bonded by a heat treatment process to a surface of the base metal substrate, the first nickel layer containing about 4 to about 6 weight percent phosphorous with the balance being essentially nickel; and a second nickel layer deposited onto the first layer, the second nickel layer containing about 8 to about 12 weight percent phosphorous with the balance being essentially nickel, wherein the first and second layers are formed by electroless plating. In this manner, adhesion is maximized without degrading the properties of the second layer such as corrosion resistance and ductility. Also disclosed are processes for forming the multilayered nickel phosphorus coatings.
