ABSTRACT:
Polycrystalline diamond has non-uniform impurity concentration along the direction of thickness. The diamond near the rake surface has a lower impurity concentration. The diamond near the fixation surface has a higher impurity concentration. The diamond with the higher impurity concentration near the fixation surface alleviates strong stress or absorbs external shock. Owing to the higher impurity concentration of diamond near the fixation surface, the diamond tool excels in chip resistance or toughness. The diamond with a lower impurity concentration near the rake surface heightens abrasion resistance, adhesion resistance and strength.
