- 摘要：
- The local pitting corrosion behavior of the pure aluminum in 3.5% NaCl
solution was characterized by electrochemical noise analysis technique.
The corrosion processes for aluminum were studied in detail by analyzing
time-domain and frequency-domain characteristics of electrochemical
noise together with morphology features. The results show that the
time-domain spectroscopy of the electrochemical noise can be used to
predict the occurrence of local corrosion and qualitatively distinguish
the type of corrosion. It was found that the current standard deviation
sigma_I, noise resistance R_n and current white noise levels W can
reflect the corrosion intensity. When the corrosion occurs, sigma_I and
W tend to increase, but R_n tends to decrease.
