| Abstract | Corrosion behavior of Zr55Al10CU30Ni5 amorphous alloy in 3.5%NaCl solution was studied by potentiodynamic polarization experiments and electrochemical impedance spectroscopy (EIS). The potentiodynamic polarization experiments showed that the amorphous alloy has a high corrosion resistance in 3.5%NaCl solution and its anodic reaction has a passive characteristic. The amorphous alloy happened pitting corrosion when the applied polarization potential was higher than the pitting corrosion potential. EIS experimental results showed that amorphous alloy has very high charge transfer reaction resistance when the alloy was in the states of cathodic polarization, open circuit potential (OCP) and passive potential, and the EIS consisted of only single large semi-circles, manifesting a high corrosion resistance. When the alloy was in the states of the vicinal zone of pitting and pitting corrosion zone, its EIS consisted of two and three time constants respectively. When the alloy was immersed in 3.5%NaCl solution for about 12h, its corrosion resistance decreased greatly. |
