Methods For Extracting Titanium Metal And Useful Alloys From Titanium Oxides
US Patent:
2011009, Apr 28, 2011
Filed:
Mar 22, 2005
Appl. No.:
10/593899

International Classification:
B05D 5/00, B05D 7/00, B22F 3/02, B22D 19/00, C22B 34/12
US Classification:
427399, 427214, 419 66, 164 91, 75392
Abstract:
Titanium-containing metal is extracted from its oxide(s) by way of a redox chemical reaction with a reducing metal. Specifically, an intimate mixture of the reducing metal and the titanium-containing oxide(s) is produced, in a preferred embodiment, by forming a metal-ceramic composite material featuring these two constituents. In a preferred embodiment, the composite body is made by infiltrating the reduced metal in molten form, into a permeable mass containing the titanium-bearing oxide(s). Concurrently or subsequent to infiltration, the redox reaction is carried out to transform the composite material, thereby forming a complex intimate mixture containing one or more oxides of the reducing metal, a titanium-containing metal, which could include an alloy of titanium with the reducing metal and/or one or more intermetallic compounds of titanium and the reducing metal, and possibly also some residual reducing metal, which itself possibly contains some titanium metal. One technique for removing the titanium-containing metal is to then comminute the transformed composite material while the metal constituent is still molten, such as by high speed shearing. The dispersed ceramic constituents can then be permitted to separate, and the metal component containing the titanium can simply be decanted.

International Classification:
F16D 6902
US Classification:
192107M
Abstract:
This invention relates to metal and metal matrix composite materials that are useful as, for example, brake rotors, clutch plates and other similar uses which benefit from material properties of the invention. In the case of metal matrix composite materials, clutch plates and brake rotors made according to the invention comprise an interconnected matrix metal embedding at least one filler material. For example, the at least one filler material comprises numerous acceptable filler materials present in a sufficient quantity to provide desired performance. The brake rotors and clutch plates according to the invention further comprise a coating on the surface thereof causing the metal or metal matrix composite body to function as a substrate. The coatings may be applied by various conventional techniques. Desirable results of placing a coating on a metal or metal matrix composite substrate brake rotor or clutch plate include a significant increase in the maximum operating temperature of the brake rotor or clutch plate and/or a significant reduction in weight in comparison to conventional materials, etc.
