Beschreibung
Zusammenfassung:	At least one embodiment of a polycrystalline diamond element that may be used in machining various material includes a polycrystalline diamond body having a plurality of bonded diamond grain defining a plurality of interstitial regions, at least some of the plurality of interstitial regions at least partially occupied and/or previously occupied by at least one interstitial constituent. The polycrystalline diamond element also includes at least one leaching feature within the polycrystalline diamond body positioned and configured to reduce leaching cycle time of the at least one interstitial constituent. La presente invención se refiere al menos a una modalidad de un elemento de diamante policristalino que puede usarse para mecanizar diversos materiales que incluye un cuerpo de diamante policristalino que tiene una pluralidad de granos de diamante unidos que definen una pluralidad de regiones intersticiales, al menos alguna de la pluralidad de regiones intersticiales al menos parcialmente ocupadas y/o previamente ocupadas por al menos un constituyente intersticial. El elemento de diamante policristalino también incluye al menos una característica de lixiviación dentro del cuerpo de diamante policristalino posicionada y configurada para reducir el tiempo del ciclo de lixiviación del al menos un constituyente intersticial.
