A method of manufacturing thermally stable polycrystalline superhard components |
| abstract |
A method of making a thermally stable polycrystalline superhard member having a plurality of interbonded superhard particles and interstitial regions disposed therebetween to form a polycrystalline superhard member having a first thermally stable region and a second region , the first thermally stable region forms at least a portion of a portion of the working surface of the component, the method comprising treating a polycrystalline superhard material with a leaching mixture to remove non-superhard phase material from a plurality of interstitial regions in the first region . The treating step includes masking the polycrystalline superhard member toward and/or at the working surface along at least a portion of the peripheral surface to inhibit penetration of the leaching mixture into the superhard member through the peripheral surface of the ultrahard member. The material is preferably PCD, polycrystalline diamond, and is preferably leached after bevel formation. |
