duck - I am no tribologist but - I really cannot see the persistence from graphite (or any powder type lube) as being adequate. It does while present work pretty well - but IMO there is no film effect.
Most oils - if viscous enough and greases more so - will even when seemingly disappeared, still provide a molecular film between bearing surfaces. Modern lubes even in such thin layers can stand enormous pressures and so give good protection.
I regard graphite when present as only giving a low friction effect but under point pressure - no barrier remains.
Only my 2c y'hear :smile:
Did I say welcome yet? Darned if I did - welcome aboard :smile:
You're right about the persistance; graphite requires more diligence to keep it applied. I was sold on it in Iraq, where we found that CLP even if applied and wiped off was still too "wet." It simply turned to mud in that environment with the talcum powder-like dust. We ended up cleaning weapons (and magazines) daily, and wiping them off throughout the day.
I still use it on my waterfowl guns if I know the temp is going to be below freezing, because it seems to work a little better in those temps.
Day to day, I'm a big fan of CLP.
