摘要:

电化学噪声时域谱可以预测局部腐蚀的发生，定性地说明腐蚀发生的类型；电流标准偏差σ_I，噪声电阻R_n和电流白噪声水平W能表征腐蚀发展的剧烈程度，当腐蚀发生时，σ_I和W趋于增大，R_n趋于减小。

关键词 ：电化学噪声, 纯Al, 局部腐蚀, 时域分析, 频域分析

Abstract：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 σ_I, noise resistance R_n and current white noise levels W can reflect the corrosion intensity. When the corrosion occurs, σ_I and W tend to increase, but R_n tends to decrease.

Key words： electrochemical noise pure aluminum local corrosion time-domain analysis frequency-domain analysis
