Polycrystalline diamond cutters with working surfaces having varied wear resistance while maintaining impact strength
InactiveUS6601662B2Improve wear resistanceMaintain strengthDrill bitsConstructionsDiamond crystalPolycrystalline diamond
Disclosed is a polycrystalline diamond or diamond-like element with greatly improved wear resistance without loss of impact strength. These elements are formed with a binder-catalyzing material in a high-temperature, high-pressure (HTHP) process. The PCD element has a body with a plurality of bonded diamond or diamond-like crystals forming a continuous diamond matrix that has a diamond volume density greater than 85%. Interstices among the diamond crystals form a continuous interstitial matrix containing a catalyzing material. The diamond matrix table is formed and integrally bonded with a metallic substrate containing the catalyzing material during the HTHP process. The diamond matrix body has a working surface, where a first portion of the interstitial matrix in the body adjacent to the working surface is substantially free of the catalyzing material, and a second portion of the interstitial matrix in the body adjacent to the working surface contains the catalyzing material. The first portion of the interstitial matrix and the second portion of the interstitial matrix have substantially the same impact strength.

Nanodiamond PCD and methods of forming
InactiveUS20050019114A1Improve high temperature performanceReduce manufacturing costMaterial nanotechnologyPigmenting treatmentDiamond crystalPolycrystalline diamond
A nanodiamond tool, including a mass of sintered nanodiamond particles can be produced having improved mechanical, thermal, and electrical properties. The sintered mass can contain greater than about 95% by volume nanodiamond and greater than about 98% by volume carbon. Such nanodiamond tools can be formed by assembling a mass of nanodiamond particles and sintering the mass of nanodiamond particles to form a sintered mass. Prior to sintering, the mass of nanodiamond particles can be substantially free of non-carbon materials such as metal binders, sintering aids or the like. Upon sintering, the nanodiamond particles sinter together at high pressures and lower temperatures than those typically required in producing polycrystalline diamond compacts with diamond crystals of a larger size. The absence of non-carbon materials improves the high temperature performance and reliability of the nanodiamond tools of the present invention.
