Abstract Al-Zr-M (M=Fe, Ce and Nd) alloys were prepared by arc melting. The structures of alloys were identified by X-ray diffraction (XRD). The electrochemical behavior of these alloys was studied by potentiodynamic polarization in 3.5% NaCl solution．The surface morphology of samples after corrosion was analyzed by optical microscope. The results show that the passivation in 3.5% NaCl solution for Al-Zr alloys with rare earth addition was easier than that without addition. The ability of corrosion resistance of alloy with Nd is superior to that with Ce. Because of active polarization, the current density of cathodic polarization for A1-Fe-Zr alloy was large, and low corrosion resistance was low.
