In the present work it was shown that Niobium carbide (NbC) offers a competitive profile compared to tungsten carbide (WC) as cutting material regarding ist wear resistance preferably in metal cutting processes.
In this study the tool behavior of two NbC substrates, defined as NbC0.88-12Co and NbC1.0-12Ni4Mo4VC respectively, is compared to commercial, submicron grained WC-6Co tool material.
