Influence of sintering conditions on the properties of polycrystalline cubic boron nitride
Soviet Powder Metallurgy and Metal Ceramics, 1986For 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, 2014Wear 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, 2002The 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.

A Review of Polycrystalline Cubic Boron Nitride Cutting tool Developments and Application
1993This paper reviews published literature on the manufacture and application of polycrystalline cubic boron nitride (PCBN) cutting tools. More specifically, it details the various commercial CBN products, their composition/microstructure and physical properties, together with workpiece/material applications and associated machinability data. In addition,
