Synthesis and characterization of high friability and high oxidation resistance diamond abrasives containing cBN particle

In this study, we synthesized diamond grains containing cBN particles by adding cBN particles during the synthesis of diamond by the high-pressure high-temperature (HPHT) method. The obtained particles were characterized by Raman spectroscopy. We also investigated the mechanical strength and oxidation resistance of the abrasive grains in air. The results confirmed that cBN particles were trapped inside the diamond grains. In addition, compared with commercial diamond abrasive grains, these diamond particles had high friability and high oxidation resistance in air. These diamond particles have potential as a new diamond abrasive.
