By the way, the water is stagnant. There are numerous crevices as well. There is a particular abundance of crevices on the Ferralium part itself, but also some on the 625.
I have just realized that fouling of either part will also hampber the function of the device. I am concerned about...
The contact with the Ferrallium is not electrically sound, it is simple contact. Isn't crevice corrosion and pitting of the spring in other areas still possible if the connection to the ferallium is not good? I know that we always check anode connections on our pipelines to ensure extremely low...
Thank you for the resources. I have already read everything available in those places. It was actually the Special Metals literature that got me so worried in the first place.
I really need some more input on this, if anyone else has insight to offer.

I am reviewing a design that uses an Inconel 625 spring made from 0.008" wire stock to hold some small Ferralium 255 cogs in place. The spring is required to stay intact for 25 years, submerged in Gulf of Mexico seawater. I am concerned that even a single pit could cause the spring to fail...
