Abstract

The polycrystalline diamond, cubic boron nitride and cubic boron nitride-diamond with homogeneous microstructure and strong direct bonding were obtained by the reaction sintering of diamond-graphite/WC-Co, cBN-hBN/Mg3B2N4 and cBN-graphite/WC-Co systems. In these systems, sintering proceeded via transformation from graphite to diamond structure. The sintering process of these systems was discussed based on the observation by SEM, EPMA, X-ray diffraction, Raman spectroscopy, micro-Vickers hardness test and scanning Auger spectroscopy.
