Galling Phenomena: Info Sources
Galling Phenomena: Info Sources
(OP)
Folks...
I need some good references on the phenomena of metal-to-metal galling. Web-based or text-book references, or helpful comments/discussion, would be appreciated.
My particular problems revolve around CRES and Heat-resistant alloy combinations... but my "need" is also generic ... to includes general concepts, galling-mechanisms, prevention schemes, etc... and the other typical aerospace alloys [aluminum, titanium, coppers, etc].

Galling happens when you have cold welding due to high stress and ductile materail/s coming in contact. If you select material combination which do notform cold welding, it would be easy to manage. Also consider dissimilar metal combinations, metal-polymer, metal-ceramic, if your design allows. Coating one or both the surfaces is also suitable alternatives. The coating material can be polymer or ceramic or even metallic alloy (different from the substrate or counterface material)
Refer to good books on friction and wear.

TVP... thanks for reminding me to query ASM database... found a re-print article of value, being sent to me. I think our Tech Library has the ASM Volume You noted... I will check soon.
