Hi folks-

I wonder how thick an aluminum oxide layer will be on an aluminum part when
it is NOT anodized by purpose. I have parts that have been milled by
electric discharge machining (=EDM, submersed in de-ionized water) which
may oxidize the surface faster than just air because of the oxygen that is
solved in the water.

The resulting surface roughness is about 27-30 microinches Ra (that is
below one micrometer rms) which is pretty good for EDM. Now, though, I have
difficulties in assessing the oxide layer thickness. 

Any clues?

Further: How thick can an oxide layer be made by anodizing?

Thanks in advance - David.
