Cutting elements and methods for fabricating diamond compacts and cutting elements with functionalized nanoparticles
A method of fabricating a diamond compact includes functionalizing surfaces of diamond nanoparticles with fluorine; combining the functionalized diamond nanoparticles with a non-group-VIII metal to form a particle mixture; and subjecting the particle mixture to high pressure and high temperature (HPHT) conditions to form inter-granular bonds between the diamond nanoparticles. A cutting element for an earth-boring tool includes a plurality of grains of diamond material; a plurality of diamond nanoparticles bonded to the plurality of grains of diamond material; and a non-group-VIII metal fluoride disposed within interstitial spaces between the grains of diamond material and the plurality of diamond nanoparticles. The cutting element is substantially free of a metal-solvent catalyst.
