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.
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.
