Title (EN) POLYCRYSTALLINE DIAMOND COMPACT
(FR) DIAMANT POLYCRISTALLIN COMPACT
Abstract: front page image
(EN)A polycrystalline diamond (PCD) composite compact element 100 comprising a substrate 130, a PCD structure 120 bonded to the substrate 130, and a bond material in the form of a bond layer 140 bonding the PCD structure 120 to the substrate 130; the PCD structure 120 being thermally stable and having a mean Young's modulus of at least about 800 GPa, the PCD structure 120 having an interstitial mean free path of at least about 0.05 microns and at most about 1.5 microns; the standard deviation of the mean free path being at least about 0.05 microns and at most about 1.5 microns. Embodiments of the PCD composite compact element may be for a tool for cutting, milling, grinding, drilling, earth boring, rock drilling or other abrasive applications, such as the cutting and machining of metal.
(FR)Cette invention concerne élément compact composite à base de diamant polycristallin (PCD) 100 comprenant un substrat 130, une structure à base de PCD 120 liée au substrat 130, et un matériau d'adhésion sous forme d'une couche d'adhésion 140 liant la structure à base de PCD 120 au substrat 130 ; la structure à base de PCD 120 étant thermiquement stable et ayant un module de Young moyen de 800 GPa au moins, la structure à base de PCD 120 ayant un libre parcours moyen interstitiel d'au moins environ 0,05 micron et d'au plus environ 1,5 micron ; l'écart type du libre parcours moyen étant d'au moins environ 0,05 micron et d'au plus environ 1,5 micron. L'élément compact composite à base de PCD de l'invention peut servir dans un outil de découpe, de fraisage, de perçage, de forage mécanique, de forage de roche, ou autres applications abrasives, comme la découpe ou l'usinage de métaux.
