As for galling, in a normal atmosphere that will oxidize the bare surface, at least there's some protection. I don't know if the tooth-to-tooth contact stresses are high enough to break through the natural layer of oxide and promote galling.

So...it's a cosmetic surface finish?
I don't understand why you'd anodize the gear if you're going to machine it away at the only point where it matters.
