Abstract:
A hardfacing material includes a metal matrix material and particles of crushed polycrystalline diamond material embedded within the metal matrix material. An earth-boring tool includes a body comprising particles of fragmented polycrystalline diamond material embedded within a metal matrix material. The particles of fragmented polycrystalline diamond material include a plurality of inter-bonded diamond grains. A method includes forming an earth-boring tool including a metal matrix material and particles of crushed polycrystalline diamond material.
