通过电化学测试和表面分析，研究了N80碳钢在含醋酸的CO2饱和环境中的缝隙腐蚀行为。缝隙外半电极无明显腐蚀，缝隙内半电极腐蚀严重，缝隙口出现深腐蚀凹槽。碳钢的缝隙腐蚀是由缝隙内外两个半电极之间的电偶效应引起的。随着HAc浓度的增加，缝隙内、外两个半电极之间的电偶效应增强，从而促进缝隙腐蚀。
Crevice corrosion of N80 carbon steel in CO2-saturated environment containing acetic acid (HAc) was studied by electrochemical measurements and surface analysis. No obvious corrosion is observed on the half-electrode outside crevice while severe corrosion occurs on the half-electrode inside crevice, and deep corrosion groove appears at the crevice mouth. Crevice corrosion of carbon steel is triggered by the galvanic effect between the two half-electrodes inside and outside crevice. Crevice corrosion is promoted by increasing the HAc concentration because the galvanic effect between the two half-electrodes inside and outside crevice is strengthened with the increase of HAc concentration.
