  • Patent number: 10227677
    Abstract: A titanium alloy including by mass %, a platinum group metal: 0.01 to 0.15% and a rare earth metal: 0.001 to 0.10%, with the balance being Ti and impurities. The titanium alloy preferably includes as a partial replacement for Ti, Co: 0.05 to 1.00% by mass, and the content of the platinum group metal is preferably in the range of 0.01 to 0.05% by mass. Furthermore, it is preferred that the platinum group metal be Pd and the rare earth metal be Y. Consequently, it is possible to provide a titanium alloy having corrosion resistance comparable to or better than that of the conventional art as well as good workability while offering an economic advantage with a lower content of platinum group metal or an advantage of less likelihood of corrosion growth originating at defects such as flaws that occurred in the surface.

  • Publication number: 20140193289
    Abstract: A one-dimensional titanium nanostructure and a method for fabricating the same are provided. A titanium metal reacts with titanium tetrachloride to form the one-dimensional titanium nanostructure on a heat-resistant substrate in a CVD method and under a reaction condition of a reaction temperature of 300-900° C., a deposition temperature of 200-850° C., a flow rate of the carrier gas of 0.1-50 sccm and a reaction time of 5-60 hours. The titanium nanostructure includes titanium nanowires, titanium nanobelts, flower-shaped titanium nanowires, titanium nanorods, titanium nanotubes, and titanium-titanium dioxide core-shell structures. The titanium nanostructure can be densely and uniformly grown on the heat-resistant substrate. The present invention neither uses a template nor uses the complicated photolithographic process, solution preparation process, and mixing-coating process. Therefore, the process scale-up, cost down, and the simplified production process are achieved.

  • Patent number: 8771439
    Abstract: The invention is directed to a method for producing a titanium aluminide intermetallic alloy composition having an improved wear resistance, the method comprising heating a titanium aluminide intermetallic alloy material in an oxygen-containing environment at a temperature and for a time sufficient to produce a top oxide layer and underlying oxygen-diffused layer, followed by removal of the top oxide layer such that the oxygen-diffused layer is exposed. The invention is also directed to the resulting oxygen-diffused titanium aluminide intermetallic alloy, as well as mechanical components or devices containing the improved alloy composition.

  • Publication number: 20140161660
    Abstract: A titanium alloy including by mass %, a platinum group metal: 0.01 to 0.15% and a rare earth metal: 0.001 to 0.10%, with the balance being Ti and impurities. The titanium alloy preferably includes as a partial replacement for Ti, Co: 0.05 to 1.00% by mass, and the content of the platinum group metal is preferably in the range of 0.01 to 0.05% by mass. Furthermore, it is preferred that the platinum group metal be Pd and the rare earth metal be Y. Consequently, it is possible to provide a titanium alloy having corrosion resistance comparable to or better than that of the conventional art as well as good workability while offering an economic advantage with a lower content of platinum group metal or an advantage of less likelihood of corrosion growth originating at defects such as flaws that occurred in the surface.

  • Patent number: 8709178
    Abstract: The present invention provides a titanium material for hot rolling which enables reduction of defects on the surface (in the case of a flat material or strip coil, including not only the flat surfaces but also the side surfaces and edges) due to hot rolling. The titanium material for hot rolling has dimples imparted by cold plastic deformation whose mean value of the heights (Wc) of the undulation profile elements is 0.2 to 1.5 mm and mean value of the lengths (WSm) thereof is 3 to 15 mm. The invention also provides a method of producing the titanium material and a method of hot rolling the titanium material.

  • Publication number: 20140112820
    Abstract: A beta-based titanium alloy with a low elastic modulus includes 37 wt. % to 41 wt. % niobium (Nb), 5 wt. % to 8 wt. % zirconium (Zr), and a balance of titanium (Ti), with unavoidable impurities, and having an elastic modulus of 47 GPa or lower. The beta-based titanium alloy has a much lower elastic modulus than the typical biomedical titanium alloys, and thus can resolve the problem of so-called “stress shield effect.” Therefore, the beta-based titanium alloy can be widely used as a material for general civilian goods such as eyewear frames and headsets and sports and leisure goods, as well as a biomedical material for artificial bones, artificial teeth and artificial hip joints.

    Abstract: Composite structures having a reinforced material interjoined with a substrate and methods of creating a composite material interjoined with a substrate. In some embodiments the composite structure may be a line or a spot or formed by reinforced material interjoined with the substrate. The methods typically include disposing a precursor material comprising titanium diboride and/or titanium monoboride on at least a portion of the substrate and heating the precursor material and the at least a portion of the substrate in the presence of an oxidation preventative until at least a portion of the precursor material forms reinforced material interjoined with the substrate. The precursor material may be disposed on the substrate as a sheet or a tape or a slurry or a paste. Localized surface heating may be used to heat the precursor material. The reinforced material typically comprises a titanium boron compound, such as titanium monoboride, and preferably comprises ?-titanium.
