电化学噪声技术研究X80钢的点蚀过程
An Electrochemical Noise Study of the Pitting Process of X80 Pipeline Steel
摘 要
采用电化学噪声（Electrochemical Noise，EN）方法研究了X80管线钢在NaHCO3+NaCl溶液中亚稳态与稳态点蚀特征。结果表明：在含Cl-溶液中，当试样处于点蚀亚稳态，电位与电流噪声具有典型的快速下降或上升，缓慢恢复的暂态峰（Transient）特征，噪声电流峰平均宽约5~10 s，而噪声电位峰宽为100 s。随着腐蚀时间的延长，亚稳态点蚀噪声峰数量增多，亚稳态点蚀程度加剧;当点蚀由亚稳态发展到稳态初期，电流噪声峰恢复时间变长，与电位噪声峰寿命趋于一致;而随着稳态点蚀的发展，电位与电流峰出现的频率显著增加，电位与电流峰具有很好的相位同步性。

Abstract
The characters of metastable and stable pitting of X80 pipeline steel in NaHCO3 + NaCl aqueous solution were studied by electrochemical noise (EN). The results showed that in the solution containing Cl-,when the sample was in the condition of metastable pitting, noise current and noise potential patterns had a general characteristic of fast rise (or fast down) and slow recovery. The lasting time of noise current peak was 5-10 second in average, but the lasing time of noise potential peak was 100 second. The number of metastable pitting noise peaks increased with the increase of time. And the metastable pitting was promoted. When the pitting developed from metastable state to the initial stage of stable state, the recovery time of noise current peak became longer and was gradually close to the lifetime of noise potential peak. With the development of the stable pitting, the frequency of potential and current peak increased. There was phase synchronism existing between potential and current peak.
