A POLYCRYSTALLINE SUPER HARD CONSTRUCTION AND A METHOD OF MAKING SAME |
摘要 |
<p>A polycrystalline super hard construction comprising a body of polycrystalline diamond (PCD) material and a plurality of interstitial regions between inter-bonded diamond grains forming the polycrystalline diamond material; the body of PCD material comprises a working surface positioned along an outside portion of the body; a first region substantially free of a solvent/catalysing material; and a second region remote from the working surface that includes solvent/catalysing material in a plurality of the interstitial regions. The first region extends to a depth of at least about 800 microns from the working surface into the body of polycrystalline diamond material.</p> |
