    摘要： A method of re-processing used TSP material layers to form cutting elements, bits with such cutting elements mounted on their bodies, and bits having re-processed TSP material layers attached to their bodies, as well as such cutting elements and bits are provided. The method includes providing a used TSP material cutting element having a TSP material layer and substrate, or a bit having a TSP material layer attached to the bit, removing the used TSP material layer from the cutting element or bit, cutting the used TSP material layer to a new shape, if necessary, optionally re-leaching the used TSP layer and re-using the TSP material layer to form a cutting element, or in forming a bit body. The formed cutting element may be mounted on a bit body.

    摘要： Polycrystalline diamond constructions include a diamond body comprising a matrix phase of bonded together diamond crystals formed at high pressure/high temperature conditions with a catalyst material. The sintered body is treated remove the catalyst material disposed within interstitial regions, rendering it substantially free of the catalyst material used to initially sinter the body. Accelerating techniques can be used to remove the catalyst material. The body includes an infiltrant material disposed within interstitial regions in a first region of the construction. The body includes a second region adjacent the working surface and that is substantially free of the infiltrant material. The infiltrant material can be a Group VIII material not used to initially sinter the diamond body. A metallic substrate is attached to the diamond body, and can be the same or different from a substrate used as a source of the catalyst material used to initially sinter the diamond body.

    摘要： PCD materials comprise a diamond body having bonded diamond crystals and interstitial regions disposed among the crystals. The diamond body is formed from diamond grains and a catalyst material at high pressure/high temperature conditions. The diamond grains have an average particle size of about 0.03 mm or greater. At least a portion of the diamond body has a high diamond volume content of greater than about 93 percent by volume. The entire diamond body can comprise high volume content diamond or a region of the diamond body can comprise the high volume content diamond. The diamond body includes a working surface, a first region substantially free of the catalyst material, and a second region that includes the catalyst material. At least a portion of the first region extends from the working surface to depth of from about 0.01 to about 0.1 mm.
