Thermal Conductivity of Oxidized Copper

[limct]

Hi,
Can anyone tell me how would the thermal conductivity be impacted on an oxidized copper surface.

Best regards,

You are talking about TC in direct conduction, not radiant heat transfer, right? I don't see it having a measurable impact, unless you are talking about a thin film of Cu. If you are dealing with a heat tint film that is measured in angstroms it will not impact bulk properties. If your oxide fill is thick enough to be dark and porous then it may have a significant effect. The TC of copper oxide is about 1/20 that of the metal.
