Chip formation in grinding involves high specific energy compared to other machining processes due to high negative rake angle of grains, adverse grinding process parameters and physical–mechanical properties of the workpiece material. This causes excessive friction between chip-grit and chip-bond interfaces as there are no free flow of chip between ...

Abstract In this work, a process is established for recovering cubic boron nitride (cBN) grains from fired vitrified cBN products. The abrasive grains are recovered by an acid washing technique. Two methods were used to recover the abrasive grains, namely with and without pre-heating.

Abstract The phase stability of cBN is critically dependent on the content and amount of impurities present. While studies have shown qualitatively that the addition of certain impurities can either increase or decrease the cBN-hBN phase transition temperature, studies have yet to show this effect quantitatively. This is because analytical methods to

Fabrication and properties of Mo contacts to amorphous cubic boron nitride (a-cBN) layers
Diamond and Related Materials, 1996Abstract Mo contacts of areas varying from 2.4 to 9.4 mm2 were electron beam deposited onto undoped and sulphur doped a-cBN layers. Layers were grown by the reactive pulse plasma method on oxidized, or oxidized and subsequently covered with Au, silicon substrates.

Ti-coated diamond and cBN with TiCN as the binder were used to fabricate the TDBN-TiCN series PDC with improved heat resistance, wear resistance and impact toughness by a China-type cubic high-pressure apparatus (5.5–6.5 GPa, 1450–1650 °C) for drilling ...

Growth conditions of the cubic phase cBN in boron nitride films
Thin Solid Films, 2006The nucleation and the subsequent coalescence period of the cubic phase cBN in sputter deposited BN-films is characterized by a shrinking of the film thickness. This is due to the transition of hBN into the denser cBN-phase which occurs inside a highly textured hBN base layer.
