| Abstract: | The corrosion behavior of a weathering steel 09CuPCrNi-A and a common steel F500L-Z in 3.5%NaCl solution was investigated by open circuit potential and electrochemical impedance spectrum(EIS) measurements.The results showed that the resistance of the steels increased first and then decreased with increasing soak time and tended to be steady after 1272 h. Bode charts indicated that the curves moved to low frequency and phase angle curves decreased gradually.Corrosion resistance of 09CuPCrNi-A was better than... |
