摘要
本文采用动电位扫描法研究了Ａ３钢在油田污水中的腐蚀速度，以及Ｓ２－对腐蚀速度的影响，通过测膜电位曲线的方法，研究了ＦｅＳ膜的离子选择性，阐述了ＦｅＳ膜的离子选择性对基体金属腐蚀行为的影响。研究表明，金属表面的ＦｅＳ膜是一种双极结构膜，促进腐蚀。
The corrosion behavior of A 3 steel was studied in oil, imitating waste water by mean of potential scanning.The ion selectivity of FeS film was examined by measering membrance potentials.Furthermore,the relationship between corrosion behavior of metal and ion selectivity of FeS film is determined.The results shows that FeS film on metal surface is one kind of bipolarized film and may accelerate metal corrosion.
