CBN-based cutting tools with niobium compounds as a binder phase
cBN-based materials are well known for their high chemical inertness and high performance. The variation of binder phase type and amount enable improvement of performance even more. Comprehensive investigation of the influence of type of niobium compound (NbC and NbN) as a binder phase for cBN-based materials were done. Samples were prepared by high pressure high temperature (HPHT) sintering under
