A1 - Woydt, Mathias T1 - NbC-based cermets: influence of secondary carbide addition and metal binder N2 - Full densification of Fe, Co and Ni bonded NbC based cermet’s was achieved by pressure less liquid phase sintering in vacuum for one hour at 1420°C. The hardness and toughness of the NbC matrix cermet’s can be mainly tailored by the binder composition and secondary carbide additions. Ni binder based NbC cermet’s allow the combination of high hardness and improved toughness. The addition of lesser amounts of VC/Cr3C2 in a NbC partially substituted WC-Co cemented carbide increased significantly the hardness in combination with a moderate fracture toughness.

T1 - Potentials of niobium carbide (NbC) as cutting tools and for wear protection N2 - 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. T2 - 19.
