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.

Fine grained polycrystalline abrasive material

The invention provides a tool component comprising a first layer of polycrystalline cBN material which has a rake (working) surface and a flank surface and comprises less than 70 vol % cBN; and a secondary layer across the rake surface or at least partially across the rake surface and comprising a refractory material and optionally a binder phase and optionally cBN, wherein the secondary layer has a higher resistance to crater formation than the first layer of cBN material and has a lower affinity towards iron than cBN.
