摘要：

The anodic current fluctuation during long time passivation on type 304SS in H2SO4 aq. solutions without aggressive ions was analyzed by FFT method. The observed dependence of power spectral density (PSD) on passivation potential and time can be described in terms of the nature of two kinds of bound water incorporated in the passive film. © 1990.
