It is the first time that ion-passing-selectivity through corrosion scale was discovered and the influence of ion-passing-selectivity on the corrosion rate and local corrosion behavior was .
模拟油田高温、高压CO_2腐蚀环境,研究了普通N80钢、低含Cr N80油套管钢CO_2腐蚀产物膜的结构特征,讨论了阳极反应与腐蚀产物膜结构之间的关系,提出了腐蚀产物膜离子透过选择性特征,并阐述了离子透过选择性对腐蚀速率、局部腐蚀的影响。
