(Al86Ni9La5)100-xZrx alloy ribbons (x=0, 3, 5, 7, 10) were prepared by melt-spinning. The amorphous characteristics and thermal stability of the ribbons were analyzed by X-ray diffraction (XRD) and differential scanning calorimeter (DSC). The corrosion behavior of (Al86Ni9La5)100-xZrx (x=0, 3, 5, 7) amorphous samples were investigated by electrochemical techniques in 0.01 mol/L NaCl alkaline solution. The results reveal that among the (Al86Ni9La5)100-xZrx (x=0, 3, 5, 7, 10) ribbons the (Al86Ni9La5)95Zr5 exhibits the best thermal stability, and with the content of Zr increasing, the electrochemical corrosion resistance is also enhanced
