| Abstract: | The electrochemical behaviors of passive film formed on 316L stainless steel and 690 alloy in NaOH solution were studied by potentiodynamic polarization,electrochemical impedance spectroscopy(EIS) and capacitance measurements.The results showed that there were significant differences between polarization curves of the two materials in NaOH solution.316L stainless steel had a wide passive anodic region from 100 mV to 900 mV in NaOH solution.The impedance value of the passive film on 316L stainless steel in N... |
