High Emissivity Coatings
High Emissivity Coatings
(OP)
Anyone know of High Emissivity coatings on metal substrates that also offer good abrasion resistance and low friction?

RE: High Emissivity Coatings
And why do you need low friction? A load bearing surface shouldn't be used for emission.

RE: High Emissivity Coatings
The load is very small, dealing with thin(.001") metal substrate sliding over another. Bearing load is small but has to survive over 1mil cycles of sliding back and forth about an inch each time.
RE: High Emissivity Coatings
I don't see a simple solution here.
> anodize is probably the best for a simple surface, but you'd only get about 0.88 emissivity and it's unclear that anodize would survive 1M cycles
> etched pyramidal pits prior to anodization would increase the net emissivity, but I'm not certain that the exposed part would be able to survive 1M cycles.
