TY - CONF A1 - Woydt, Mathias T1 - Status of nickel bonded niobium carbide (NbC) as a substitute for cobalt-bonded tungsten carbide (WC) as cutting tools and for wear protection N2 - Niobium is today largely available. The initial NbC grade was substoichiometric, SPS sintered and cobalt bonded. The NiMo-bonded stoichiometric NbC1.0 grades enable the substitution of cobalt by nickel, SPS by conventional sintering and NbC0.88 by NbC1.0 in view of functional properties. Nickel bonded NbC grades have improved toughnesses versus cobalt NbC grades, but lose hardness. NiMo and NiMo2C bonded NbC1.0 grades compensated the loss in hardness while keeping the toughness.
