摘要: 采用丝束电极研究了防锈油膜失效期间的电位波动现象。研究表明,防锈油膜具有自修复能力,且这种自修复能力与油溶性缓蚀剂的浓度和种类有关;采用丝束电极研究和评价防锈油膜的自修复能力是可行的。

Abstract：As a natural extension of our previous work, the novel wire beam electrode was used to study potential fluctuation of rust preventing oil film during its degradation. As a special electrochemical sensor, it remarkably improved the reproducibility of electrochemical tests. The error of electrochemical test may reduce to less than 5%. As a non-destructive and simple method, potential measurement had some advantages over other electrochemical testing methods. For example, polarization resistance measurement could breakdown the integrity of oil coating by DC current and EIS was time consuming. The electrochemical parameter and its category related to underfilm corrosion process could be measured directly using wire beam electrode. Potential fluctuation occurred on rust preventing oil film during its degradation, and the oil film had self-repairing ability. However, for the unoiled metal electrode and the electrode with base oil film, no such behavior was observed. Inhibitors in the oil film had direct effect on the self-repairing ability.

Key words： Rust preventing oil Electrochemical measurement Wire beam electrode Potential fluctuation
