Anodization of Copper

[benn121]

Hello,

I am trying to set up a copper anodization kit. I was wondering if anyone had information about copper anodization that would be helpful?

Thank you in advance.

The CuO is conductive, brown, softer -- Anodizing is useful
for Al where the Al2O3 is hard,protective layer.

Most likely the Cu would dissolve in a conductive bath
anyway.

Thank you for your response,

I actually want to anodise the copper to produce a semi-conductive layer on the surface. Can anyone help or offer any advice on this please? any help would be greatly apreaciated.

Polish, etch away dirt and CuO, heat it close to redhot
in protective gas ( Ag,N2, or CO2 ) with small amount of O2.

When surface is black, cool and soak it in dilute H4N
solution until it turns red.

In highschool ( in the 50s ) I made CuO rectifier--
it worked, if I remember with 2V about 10 mA/cm2
