Influence of Milling and Use of Ni and Al Containing Metal Binder in NbC-Based Cermets

This study presents the development of niobium carbide cermets bound to nickel and Ni-12Al (wt%). The use (wt%) Ni aims replace strategic elements such as cobalt (Co) utilized in tungsten carbide-based cermets. Cermets different compositions were processed by conventional powder metallurgy. Microstructural analysis with semi-quantitative chemical EDX, Vickers microhardness density measurement performed evaluate influence high energy milling application sintering temperature on properties these A time 20 min a planetary mill temperatures 1420 ºC or 1450 resulted homogeneous microstructures, densities close 90% hardness around 1000 HV1, showing potential for this material cutting tools.
