The morphology and the interface features of WC grains are examined by SEM and TEM in cemented carbides WC-8 wt% Co. Three compositions --the mixture {WC ΓΎ Co binder} and the mixtures with graphite or h --are studied after treatments at 1200 and 1450 C. The effect of the C content is observed both o

In this work the apparent fracture toughness of different grades of WC-Co cemented carbides has been evaluated by means of the single edge V-notched beam (SEVNB) method. The results are analysed, as a function of both the binder mean free path and the maximum steady-state crack shielding value, foll
The electrodes prepared from the sintered tungsten carbide (WC) containing 10 vol.% of nickel or cobalt or iron, with Vickers hardness > 1200 kg mm-\*, were anodically polarized in 5 x 10-r mol dm-r aqueous solution of sulphuric acid. Material from the electrodes was electrochemically studied after
Stationary electrodes prepared from the sintered tungsten carbide (WC, M) containing 10 ~01% of M = Co, Ni or Fe binder, with Vickers hardness > 1200 kg mm-', have been investigated in 0.5 M H,SO, using the Scanning Electron Microscopy (SEM) and the Electrochemical Impedance Spectroscopy (EIS) metho
