| Samples of Fe68-xCoxZr10Mo5W2B15 (x = 7, 9, 11) bulk glassy alloys were produced in a form of 1 mm diameter rods by the suction-casting technique. XRD analysis revealed good glass forming abilities (GFA) of the investigated alloys. The corrosion characterization of the amorphous rods were performed in the absence and presence of chloride ions in sulphate test-solution. Analysis of potentiodynamic polarization curves indicates that the alloys undergo passivation in the applied media. For chloride containing solutions a distinct tendency to local corrosion has been observed. High Co containing alloy (x=11) exhibits clear worsening of corrosion behaviour as compared to the two other alloys. |
