Manufacturing of Niobium carbide cermets with nickel binder and different additions of titanium carbide has been realized by colloidal processing in aqueous environment.
The tool lifes of uncoated NiMo and NiMo2C-bonded stoichiometric NbC1.0 grades under dry turning 42CrMo4 and C45E were between +30 % to + 100 % higher and up compared to WC-6Co (fine grain). Niobium is today largely available. NbC grades displayed lower dry sliding friction over WC grades.
The research and developments on niobium carbide-based hard materials generated grades, which meet the application line for tungsten carbide and showed already a very high potential for many technical applications, especially for wear protection and machining.
