Fine grained polycrystalline abrasive material

Polycrystalline diamond abrasive elements having a fine grained microstructure are produced from fine grained diamond particles and a catalyst solvent material, at least a portion of which is in the form of nanosized particles. The abrasive elements exhibit high homogeneity and exhibit significant i...

Beschreibung
Zusammenfassung:	Polycrystalline diamond abrasive elements having a fine grained microstructure are produced from fine grained diamond particles and a catalyst solvent material, at least a portion of which is in the form of nanosized particles. The abrasive elements exhibit high homogeneity and exhibit significant increases in toughness and improved wear resistance.
