Electrochemical corrosion behavior of Zr55All0Ni5Cu30 and(Zr55All0Ni5Cu30)0.97Ce0.03 bulk amorphous alloys in chloride ion containing solutions was studied by potentiodynamic polarization and electrochemical impedance spectroscopy(EIS).The results show that with the increment of chloride ion concentration in the solutions the corrosion current densities of the two bulk amorphous alloys increase,and therefore their corrosion rates become faster.Moreover,compared withZr55All0Ni5Cu30,(Zr55All0Ni5Cu30)0.97Ce0.03 has lower current densities in corresponding chloride ion solutions.Both Zr55All0Ni5Cu30 and(Zr55All0Ni5Cu30)0.97Ce0.03bulk amorphous alloys in Na2SO4 solution or in chloride ion containing solutions show passivation behavior,but passive current densities decrease with the increment of chloride ion concentrations.EIS plots of Zr55All0Ni5Cu30 is composed of single capacitive loop,while those of(
