摘要：

Electrochemical noise measurements (ENM) for SS 316L exposed to Ringer's solution have been analyzed in the frequency domain using power spectral density (PSD) and spectral noise plots. Excellent agreement between spectral noise plots and impedance spectra was observed. However the noise resistance R-n was found to be dependent on the bandwidth of the ENM and was much lower than the polarization resistance R-p. (C) 1998 Elsevier Science Ltd. All rights reserved.
