Influence of sintering conditions on the properties of polycrystalline cubic boron nitride

Soviet Powder Metallurgy and Metal Ceramics, 1986
For the purpose of a further study of the sintering process of beta-BN grains into polycrystalline compacts, a study was made of the influence of sintering temperature and grain size on the microstructure, width of the x-ray diffraction lines, and certain physical properties of polycrystalline specimens of beta-BN. Sintering of beta-BN grains occurs in

Wear Characteristics of Binder-Less Nano-Polycrystalline Diamond and Cubic Boron Nitride

Advanced Materials Research, 2014
Wear characteristics of binder-less (single-phase) nanopolycrystalline diamond (NPD) and cubic boron nitride (BL-PcBN) were investigated by rubbing them against various ceramics such as SiO2, Si3N4, Al2O3 and SiC. The wear rates of NPD and BL-PcBN against SiO2 and Si3N4 at high speed rubbing (280-360 m/min) at a loading pressure of 55 MPa (starting ...

Effect of grain boundaries on iron distribution in polycrystalline cubic boron nitride

Journal of Physics: Condensed Matter, 2002
The influence of grain boundaries on local electronic states and the distribution of 57Fe ions in cubic boron nitride (c-BN) polycrystals has been investigated as a function of technological processing. The study was performed on two sets of c-BN samples: (1) prepared by catalytic synthesis and (2) synthesized by direct phase transformation.
