摘要	The corrosion behaviour of AM60 containing Ce or La (AMRE1) under thin electrolyte layers (TEL) in 3.5 wt.% NaCl solution was investigated by cathodic polarization and EIS. The results indicated corrosion resistance was enhanced by TEL decrease until 100 pm. There were three kinetic regions in polarization curves of AMRE1, whereas the second region disappeared for AM60. Meanwhile, EIS results showed capacitive loop at Us for AMRE1 appeared under 200-300 mu m thickness. The presence of second regions in polarization curves and capacitive loops at Us in EIS was attributed to performance of new phases (gamma) as indicated in microstructural characterization.
