Abstract
Polarization and passivation behavior of three Zr-based BMGs, i.e. Zr58.3Al14.6Ni8.3Cu18.8, Zr58Al16Ni11Cu15 and Zr57.5Al17.5Ni13.8Cu11.3 were investigated in 3% NaCl aqueous solution. Electrochemical investigations were carried out by potentiodynamic polarization method at room temperature. The corroded sample surfaces were examined using scanning electron microscope having energy dispersive spectroscopy (EDS) attachment. The results of the present investigation revealed that Zr58Al16Ni11Cu15 and Zr57.5Al17.5Ni13.8Cu11.3 BMGs having relatively larger supercooled liquid region (ΔTx) and pitting overpotential (ηpit) values exhibit low corrosion current density (icorr) and corrosion penetration rate (CPR) values.
