Sintered cataltyic or absorbent metallic product and method for sintering metallic powders

Abstract: The present invention relates to a method for sintering oxidized titanium powder and an active metallic component containing oxidized molybdenum as a binder for oxidized titanium granules. The active metallic component comprises one or more than one selected from a group consisting of V 2 O 3 , Fe 2 O 3 , WO 3 , Co 2 O 3 , NiO, Cr 2 O 3 , CeO 2 , SnO 2 , CuO, MoO 3 , Pt, Pd, Rh, Ru, Ir and Re. The method comprising the steps of: depositing vaporized oxidized molybdenum on the oxidized titanium powder in an atmosphere of molybdenum vapor at temperatures of 460° to 650° C., forming a powdery mixture comprising the oxidized titanium powder with the deposited oxidized molybdenum and said active metallic component, adding water sufficient to make a viscous material of the powdery mixture, kneading the viscous material, shaping an article by using the viscous material, and calcining the article to produce a product.

Corrosion-resistant iron-base material and a process for producing same

Abstract: A corrosion-resistant iron-base material coated on at least a part of the surface thereof with a layer of a titanium-nickel alloy containing 5-45% by weight of nickel. This corrosion-resistant iron-base material is produced by applying a viscous coating liquid containing titanium powder, nickel powder and a binder onto the surface of an iron-base alloy and then heating the iron-base alloy at a temperature of 900°-1200° C. under vacuum so as to form on the surface thereof a layer of the titanium-nickel alloy containing 5-45% by weight of nickel.

Consolidation of Titanium Powder to Near Net Shapes.

Abstract: : This program was conducted to develop the technology necessary to establish a cost effective approach to the production of titanium alloy parts for both aircraft engine and airframe applications. This approach was based on a PM near-net shape process utilizing ceramic mold techniques in conjunction with HIP (Hot Isostatic Pressing) to a minimum machining envelope. Program objectives included: (1) the optimization of an existing PM process for the HIP of near-net shapes of titanium using low-cost tooling; (2) the reduction of the process to an efficient, cost effective, manufacturing procedure; and (3) thorough characterization of the end product. In cooperation with General Electric (GE) and McDonnell-Douglas (MCAIR) as sub-contractors, representative components and alloys were selected for this program. These were a Ti-17 compressor stub shaft and a Ti-6-4 keel splice former. Hot Isostatic Pressing parameters were optimized for both the Ti-17 and Ti-6-4 alloy using the ceramic mold process. SiO2 was chosen as the most promising mold material. The ability to produce near-net shapes of both engine and airframe components was successfully demonstrated. Both parts exhibited comparable properties to cast and wrought material with the exception of Low Cycle Fatigue requirements on the engine stub shaft. The results indicate that a potential exists for the HIP process to reduce both input material and machining costs compared to current cast and wrought product.

Lower titanium oxide pigment prepn. - by heating titanium di:oxide powder and metallic titanium powder and use in cosmetics, paints and printing inks

Abstract: Colouring compsn. contains a brownish black or black pigment consisting of pulverised particles of a lower Ti oxide having formula TinO2n-1 (I) (where n is integer 1 to 100). (I) is prepd. by (a) mixing a TiO2 powder, having particle size 0.01-1 mu, with metallic Ti powder, having particle size =10 mu, in mol. ratio 1-199:1, and (b) heating the mixt. in vacuo or in a reducing atmos., pref. to 500-1200 (600-1000) degrees C, for 1-20 hrs. (I) is used in cosmetics, partic. make-up cosmetics, paints, printing inks (claimed) and in pigment pastes. (I) can be used as pigments for colouring rubber and plastics. (I) mix well with other powders; are stable, easily used and prepd. (I) are non-toxic, i.e. do not irritate skin and eyes, and have low acute oral toxicity, e.g. LD50 25 ml/kg when used as a 20 wt. % suspension of TiO or Ti2O3.
