Material Treated on Ansys

[Daniele1989]

Hi all,
is it possible to perform a calculation with a material treated?
I need to evaluate a Aluminium 6082 Anodized 10um. According to you is it possible to create a sort of skin, or i have to use different materials data to the base one, or treatment?

Thank you!

I found "surface coating" command, in geometry section
