Abstract: Polycrystalline diamond composites comprise a polycrystalline diamond body having a plurality of ultra-hard discrete regions dispersed within a polycrystalline diamond second region. The plurality of discrete regions has an density different from of the polycrystalline diamond second region. A metallic substrate can be joined to the body. The discrete regions can be relatively more thermal stable than, have a higher diamond density than, and/or may comprise a binder material that is different from the polycrystalline diamond second region. Polycrystalline diamond composites can be formed by combining already sintered granules with diamond grains to form a mixture, and subjecting the mixture to high pressure/high temperature conditions, wherein the granules form the plurality of discrete regions, or can be made by forming a plurality of unsintered granules, combining them with diamond grains to form a mixture, and then subjecting the mixture to first and second high pressure/high temperature conditions.
Patent CA-2606197-A1 (CA)
Inventor: BARRON WES
IPC: B28D5/00
Filed: 2005-08-26
Abstract: A method and an apparatus for laser marking indicia in the volume of gemstones such as diamonds, the indicia being made up of a plurality of microscopic dot-shaped marks whose build-up can be initiated by exposing naturally-occurring internal defects or impurities in the volume of a gemstone to a tightly focused train of laser pulses. Authentication data is encoded in the gemstone from the relative spatial arrangement of the dot-shaped marks that form the indicium. Taking advantage of the presence of otherwise invisible defects in the gemstone allows for inscribing indicia with laser pulses carrying energies substantially lower than the threshold energy required for inscribing in the volume of a perfect gemstone material. The marking process is then much less susceptible to inflict damages to the surface of the gemstone, and the marking can be performed using a broad variety of femtosecond laser systems. The dot-shaped marks engraved at a depth below the surface of a gemstone can be made undetectable with the unaided eye or with a loupe by limiting their individual size to a few micrometres, while devising indicia made up of only a few marks.  As a result, the marking does not detract from the appearance and value of the gemstone. The procedure for laser marking accounts for the random spatial distribution of the defects present in natural gemstones as well as for their strongly localized character. The presence of an indicium can be detected by using a dedicated optical reader that can be afforded by every jewellery store.
