管线钢内壁局部腐蚀过程的微区电化学表征

Localized Electrochemical Characterization of Local Corrosion Process for Inner Wall of Pipeline Steel

本文中,作者结合CO_2腐蚀研究成果和薄液膜腐蚀的特征,采用先进微区电化学手段——丝束电极法,研究了常温浸泡条件下、薄液膜条件下以及温度升高15℃时浸泡条件下管线钢的局部腐蚀情况,研究了管线钢在浸泡条件下与薄液膜下不同的腐蚀行为。

In this paper, we combined the results of CO2 corrosion research and characteristics of thin liquid film corrosion, used the advanced localized electrochemical method- Wire Beam Electrode, studied the local corrosion of pipeline steel under soaking at room temperature and under the condition of thin liquid film and soaking at 15 degrees C. We also studied corrosion behavior of pipeline steel under immersion condition and thin liquid film.
