Can anybody tell me what the functional temperature range is for NFC coatings?

[Howard]

I'm talking about near-frictionless carbon films. At which temperatures does this material lose its properties?

this doesn't answer your question but according to:

linky

it's good up to at least 440° C.

"An NFC film coating was applied to the radial journal and thrust air bearings of a turbocompressor, a component that experiences numerous stop/start cycles. Frictional force on the 440° C steel material was reduced by four times, and the linear wear rate was reduced by two orders of magnitude."

 

[Howard]

In that case it's probably good over 700 degrees Celcius. Turbocompressors can get superhot.

 

[unclebabar]

are you going tell us what you're going to use it for?

 

[Howard]

No.
