Detailed microstructure of a cBN based cutting tool material

The microstructure of a commercial polycrystalline cubic boron nitride (PCBN) tool material was studied using scanning electron microscopy with energy-dispersive X-ray analysis and transmission electron microscopy with electron energy loss spectroscopy and energy filtered TEM. These results were compared with results from X-ray diffraction and thermodynamic calculations.

Introduced in the early 1960s, this is the second hardest material available after diamond. cBN tools may be used either in the form of small solid tips or or as a 0.5 to 1 mm thick layer of of polycrystalline boron nitride sintered onto a carbide substrate under pressure. In the latter case the carbide provides shock resistance and the cBN layer provides very high wear resistance and cutting
