  • Publication number: 20110014488
    Abstract: Fine-gained (average grain size 1 mm to 1,000 nm) metallic coatings optionally containing solid particulates dispersed therein are disclosed. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Fetch strengthening and have low linear coefficients of thermal expansion (CTEs). The invention provides means for matching the CTE of the fine-grained metallic coating to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.

    Abstract: A coating process and system for an article having a substrate formed of a metal alloy that is prone to the formation of a secondary reaction zone (SRZ). The coating system includes an aluminum-containing overlay coating and a stabilizing layer between the overlay coating and the substrate. The overlay coating contains aluminum in an amount greater by atomic percent than the metal alloy of the substrate, such that there is a tendency for aluminum to diffuse from the overlay coating into the substrate. The stabilizing layer is predominantly or entirely formed of at least one platinum group metal (PGM), namely, platinum, rhodium, iridium, and/or palladium. The stabilizing layer is sufficient to inhibit diffusion of aluminum from the overlay coating into the substrate so that the substrate remains essentially free of an SRZ that would be deleterious to the mechanical properties of the alloy.

    Abstract: A coating process and system suitable for use on components subjected to high temperatures. The coating system includes an overlay coating of predominantly B2 phase rhodium aluminide (RhAl) intermetallic compound containing about 25 to about 90 atomic percent rhodium, about 10 to about 60 atomic percent aluminum, optionally up to a combined total of about 25 atomic percent of one or more platinum group metals chosen from the group consisting of platinum, palladium, ruthenium, and iridium, and up to about 20 atomic percent of the base metal and alloying constituents of the substrate. The RhAl intermetallic coating may serve as an environmental coating, a diffusion barrier layer for an overlying environmental coating, or both, with or without an outer ceramic coating.

  • Publication number: 20080182121
    Abstract: The invention is a laminate made of very thin copper sheet preferably between 0.0005 and 0.01 inches thick, aluminum sheet preferably between 0.004 and 0.04 inches thick, and adhesive between the copper and aluminum sheets. The cost of the aluminum, adhesive, and the manufacturing process combined are much less expensive than solid copper sheet of 0.020 inches in thickness. However, when the copper sheet of the laminate is on the outside, the aesthetic qualities are indistinguishable from heavyweight solid copper sheet.

  • Patent number: 7393596
    Abstract: When an aluminum plate is bonded directly to a ceramic substrate by cooling and solidifying molten aluminum which is injected into a mold so as to contact the ceramic substrate arranged in the mold, an additive, such as a TiB alloy, Ca or Sr, for decreasing the grain size of the aluminum plate to 10 mm or less while preventing the drop in thermal conductivity of the aluminum plate from the thermal conductivity of a pure aluminum plate from exceeding 20% of the thermal conductivity of the pure aluminum plate is added to the molten aluminum. When an aluminum alloy plate of an aluminum-silicon alloy is bonded directly to a ceramic substrate by cooling and solidifying a molten aluminum-silicon alloy which is injected into a mold so as to contact the ceramic substrate arranged in the mold, an aluminum-silicon alloy containing 0.1 to 1.5 wt % of silicon and 0.03 to 0.10 wt % of boron is injected into the mold.

  • Patent number: 7294411
    Abstract: The invention relates to a brazing sheet product comprising a core sheet, a clad layer on said core sheet made of an aluminum alloy containing silicon in an amount in the range of 4 to 14% by weight, an optional layer comprising nickel on the outersurface of said clad layer, and a diffusion layer comprising nickel-tin alloy on the outer surface of said nickel layer. The invention further relates to a method of manufacturing such a brazing product comprising the process step of plating different metal layers and subjecting the plated brazing product to an annealing treatment by holding the plated brazing product at a temperature in the range of 100 to 500° C. for a period of 1 sec. to 300 minutes to form a diffusion layer comprising nickel-tin alloy on the outer surface of said layer comprising nickel.

  • Patent number: 7244512
    Abstract: A method of manufacturing electric machines comprised of geometrically patterned arrays of permanent magnets, soft magnetic materials, and electrical conductors deposited by kinetic spraying methods directly atop a carrier. The magnets and planar coils of the present invention may be integrally formed atop carriers to form electrical machines such as motors, generators, alternators, solenoids, and actuators. The manufacturing techniques used in this invention may produce highly defined articles that do not require additional shaping or attaching steps. Very high-purity permanent and soft magnetic materials, and conductors with low oxidation are produced.

  • Patent number: 7238429
    Abstract: Performance and reliability of microelectromechanical system (MEMS) components enhanced dramatically through the incorporation of protective thin film coatings. Current-generation MEMS devices prepared by the LIGA technique employ transition metals such as Ni, Cu, Fe, or alloys thereof, and hence lack stability in oxidizing, corrosive, and/or high temperature environments. Fabrication of a superhard, self-lubricating coating based on a ternary boride compound AlMgB14 is described in this letter as a potential breakthrough in protective coating technology for LIGA microdevices. Nanoindentation tests show that hardness of AlMgB14 films prepared by pulsed laser deposition ranges from 45 GPa to 51 GPa, when deposited at room temperature and 573 K, respectively. Extremely low friction coefficients of 0.04-0.05, which are thought to result from a self-lubricating effect, have also been confirmed by nanoscratch tests on the AlMgB14 films.

  • Patent number: 7211333
    Abstract: The present invention is to provide a resin-forming mold having high releasability and permitting a production without increasing production costs. The resin-forming mold can be used to produce a resin-molded product having minute uneven portions on a front face thereof, such as a surface light source device-use light guide for a liquid crystal display, an aspherical micro-lens, micro-Fresnel lens and an optical disk. In the stamper (resin-forming mold) 10 provided with an electroformed layer 11 and a conductive film 12 formed on the electroformed layer 11, the front face layer 12c of the conductive film 12 is formed of aluminum and a back face 12d is formed of nickel as an electroconductive metal. In addition, the constituent composition of the aluminum and the nickel continuously changes from the front face 12c toward the back face 12d. The front face 12c may be formed of aluminum and oxygen. The aluminum may combine with the oxygen to form an oxide of aluminum.

  • Patent number: 7169478
    Abstract: Multinary alloys, in particular for use as coatings, if appropriate in combination with other types of layers, for components which are exposed to high temperatures and corrosive gases. The alloys are of the general form: Al—Ni—Ru-M, where at least one B2 phase is present, the aluminum content being in the range from 26–60 atomic percent and where M may be one or more metals and/or semimetals selected from the group consisting of: precious metal, transition metal, rare earths, semimetal. Multinary alloys of this type are very stable with respect to oxidation, have a low thermal conductivity and in particular have similar coefficients of thermal expansion to superalloys, which are usually used as substrates for protective coatings of this type in gas turbine components.
