Superhard pcBN materials with chromium compounds as a binder
Procedia Manufacturing, 2018 Superhard cBN-based materials with Cr3C2, Cr2N and CrB2 binders were sintered in a high-pressure high-temperature (HPHT) toroidal apparatus under a pressure of 7.7 GPa and in the temperature range of 1600-2450°С. Initial mixtures of three compositions were chosen with 60 vol.% of cBN, 35 vol.% of binder phase and 5 vol.% of Al.
