    摘要： Thermally stable diamond constructions comprise a diamond body having a plurality of bonded diamond crystals, a plurality of interstitial regions disposed among the crystals, and a substrate attached to the body. The body includes a working surface and a side surface extending away from the working surface to the substrate. The body comprises a first region adjacent the side surface that is substantially free of a catalyst material and that extends a partial depth into the diamond body. The first region can further extend to at least a portion of the working surface and a partial depth therefrom into the diamond body. The diamond body can be formed from natural diamond grains and/or a mixture of natural and synthetic diamond grains. A surface of the diamond body is treated to provide the first region, and before treatment is finished to an approximate final dimension.

    摘要： The present invention concerns processes for etching a porous titanium foam or porous titanium alloy foam where a clean, dry foam product is immersed into an aqueous acid solution comprising about 0.5 to about 5 volume percent HF and about 5 to about 20 volume percent HNO3 for a time sufficient to achieve a desired surface roughness and heating the etched foam to remove residual titanates. The etching process increases the porosity at the surface of the foam but the etchant does not penetrate fully into the interior of the foam so that adequate mechanical properties are maintained. The etching process also increases the coefficient of friction at the foam surface. The foam may comprise an open-celled orthopaedic or dental implant, or may comprise a coating on the surface of a substrate.

    摘要： Thermally stable diamond constructions comprise a diamond body having a plurality of bonded diamond crystals and interstitial regions disposed among the crystals. A metallic substrate is attached to the body. The body includes a first region substantially free of a catalyst material that extends a partial depth from a surface into the body, and a second region that includes the catalyst material. The body can include natural diamond grains and/or a blend of natural and synthetic diamond grains, and is treated to form the first region. Before treatment, a portion of the body to be treated is finished to an approximate final dimension so that the depth of the first region of the finished product is substantially the same as when treated. During treatment, catalyst materials as well as non-catalyst metallic materials are removed from the diamond body to provide a further enhanced degree of thermal stability.

    摘要： A method for manufacturing valve metal anodes of electrolytic capacitors by deoxidizing the anodes using Mg vapor in a deoxidizing furnace, removing the anodes from deoxidizing furnace, placing them in sintering furnace, sintering at temperature lower than the temperature conventionally used for sintering in vacuum, and leaching of Mg oxide off the anode surface. The process limits free oxygen and improves morphology of valve metal anodes, which results in improved performance of electrolytic capacitors with these anodes. The process does not require any special equipment or maintenance operations and, thereby, is highly productive due to performing deoxidizing and sintering in traditional deoxidizing and sintering furnaces.

    摘要： An aluminum composite material has a surface structure in which a part of lubricative granules projects by 2 μm to 25 μm from the surface of the aluminum alloy base material. The lubricative property of the lubricative granules is utilized sufficiently, and the abrasion of the aluminum alloy base material can be prevented. Further, according to a manufacturing method of the aluminum composite material where the surface of the aluminum alloy base material is eroded with a etching solution, a level of erosion of the aluminum alloy base material can be easily adjusted and a surface structure from which the lubricative granules project can be formed sufficiently.
