Be aware that in most places you need to have a PE license in order to perform engineering/design work as a freelancer. Check your...
you can buy PEEK screws from Misumi, by the way.
yep, I would also recommend PEEK
I also use the Geo-Metrics books by Lowell Foster. Very good books.

It's a very interesting case! If you do find out why, I would love to know.
If you could sketch the mechanism that would definitely help. What material is the spring made of and how many cycles has it encountered between...
The moment of inertia of the parts about the turning axis will matter also, as will the acceleration applied.
Bellville springs are nonlinear and follow force/displacement curves that often look much like your 'worn' curve. I suspect the difference has to...
