Unclesyd,
We are in the process of having the suspect component fabricated from Nitronic-60, as it looks to have the highest galling resistance of the SS family. We don't have a friction/wear expert in our company, so the Nitronic material selection was based on a threshold galling stress table...
I'm working on a biomedical device that uses unlubricated sliding surfaces as a short (0.050")declutch mechanism. I inherited the design, which currently uses a mixture of stainless steels as the components and experiences galling during the declutch. Other than basic calculations for Hertz...
