The Federal Institute for Materials Research and Testing (BAM) and the Institute for Machine Tools and Factory Management (IWF) of the Technical University Berlin analyzed the suitability of various NbC types in comparison to tungsten carbide (WC) for use as a tool in cutting processes. The focus was placed on the optimization of the functional profile of NbC-based cutting materials with reproducible industrial production.
Microstructure and wear behavior of improved NbC cermets for (BS-1452) grey cast iron machining
(2017)
Tungsten carbide (WC) and cobalt (Co) based cermets are the most successful commercial cermets beacuse of the good combination of physical, mechanical and behavioral properties. Niobium carbide (NbC) has good mechanical and physical properties, such as high hardness, very high melting point and low density. SPS refined the NbC grains and increased the hardness, while substitution of Co with Ni improved the fracture toughness.
