yes many are but not Al2O3

Sorry about that, I was just under impression that many oxides are blackish in color e.g. nickel iii oxide or copper ii oxide. I work in the electroplating company BTW and we do get oxidation rejections after plating and they look black or very dark

Let's see, maybe the substrate underneath the coating is the one that oxidizes if the coating becomes porous through constant rubbing.
