Identification of the &ggr;-phase alumina is made by X-ray diffraction. Reflexes from the (400) and (440) planes occurring at the 2&thgr;0- angles 45.8 and 66.8 degrees when using CuK&agr; radiation identify the &ggr;-phase Al2O3. The alumina layer is also very strongly textured in the [440]-direction. The Al2O3 layer is virtually free of cracks and halogen impurities. Furthermore, the Al2O3 layer gives the cutting edge of the tool an extremely smooth surface finish.

  • Patent number: 6649561
    Abstract: A titania-coated honeycomb catalyst matrix is provided for the ultraviolet-photocatalytic oxidation of organic pollutants in a flowing fluid. A honeycomb-shaped skeletal structure (12) has a thin, lightweight substrate (18) of metal or ceramic, typically an aluminum alloy, and a surface coating (20) of photocatalyst, such as titania. The photocatalyst (20) is bonded to the substrate (18) via a thin oxide layer (18′) on the substrate. The oxide layer (18′) may be grown on the substrate. The photocatalyst coating (20) is made by mixing (30) titania powder in a TiO2 sol-gel to form a titania slurry. The substrate with oxide layer is coated (30) with the titania slurry and then heat treated (31). The photocatalyst coating (20) is typically applied to substrate sheets (40, 60, 62) preformed for assembly into a honeycomb-shaped skeletal structure (12) having an array of parallel cells (46, 46′).

    Abstract: A method for making aerospace face seal rotors reinforced by rhenium metal, alloy, or composite in combination with silicon carbide or other ceramic. The resulting rotor also is disclosed. Ceramic grains, preferably silicon carbide (SiC), are mixed with powdered metallic (PM) binder that may be based on a refractory metal, preferably rhenium. The mixture is applied to a rotor substrate. The combined ceramic-metal powder mixture is heated to sintering temperature under pressure to enable fusion of the ceramic in the resulting metal-based substrate. A load may then be applied under an elevated temperature. The resulting coated rotor can exhibit high hot hardness, increased durability and/or high hot wear resistance, as well as high thermal conductivity.

The coating structure of the flakes and foils includes a reflector layer, a dielectric layer on the reflector layer, and a titanium-containing absorber layer on the dielectric layer. The pigment flakes and foils exhibit a discrete color shift so as to have a first color at a first angle of incident light or viewing and a second color different from the first color at a second angle of incident light or viewing. The pigment flakes can be interspersed into liquid media such as paints or inks to produce colorant compositions for subsequent application to objects or papers.

  • Publication number: 20030203169
    Abstract: The present invention relates generally to a new ceramic structure and process thereof. Basically, the present invention relates to a structure and method for forming laminated structures and more particularly to a structure and method for fabricating multi-layer ceramic products using very thin green sheets and/or green sheets with very dense electrically conductive patterns on top of a stronger support sheet. The structure and method of the present invention enables the screening, stacking and handling of very thin green sheets and/or green sheets with very dense metallized patterns in the manufacture of multi-layer ceramic packages. The thin green sheets were tacked/bonded to thicker and stronger support sheets to form a sub-structure which had excellent stability in screening and enabled further processing. The sheets are anchored or pinned in such a way as to allow the processing of the green sheet with the subsequent easy removal of the support sheet.
