Two different grades, WC-20 vol.% Ni and Co cemented carbides, respectively were systematically investigated concerning their microstructure, binder composition, corrosion behavior. SEM-EBSD analysis verified that both grades have similar WC grain sizes (0.9–1.1 μm). AES confirmed the phase of respective grade is an alloy Ni-W Co-W concentration W in Ni- Co-binder 21 10 at. %, respectively. In ...

Cemented carbides, including coated cemented carbides, account for 75% of the cutting tools market because of their features such as high hardness, toughness, and the responsiveness to iron, through the use of tungsten carbide for their main hard phases and cobalt for their bonding metals. The consumption of tungsten continues to increase as the amount of carbide tool production increases with ...
