Dear Yuqing Xu thank you for your very interesting technical question which is certainly of great practical importance. As an inorganic chemist I have been mainly involved in rare-earth metal chemistry. Thus I would not call myself a proven expert in the field of corrosion. However, I can suggest to you a potentially useful article which I just found. Please have a look at this paper:
The corrosion damage of an organic coating accelerated by different AC-DC-AC tests
Article The corrosion damage of an organic coating accelerated by di...
Also please see:
Damage assessment of the corrosion-resistant performances for organic coating systems after accelerated tests using analytic hierarchy process
Article Damage assessment of the corrosion-resistant performances fo...
Unfortunately I don't have access to the full texts of the two paper.
The following relevant article is freely available as public full text:
