Are you sure about that? I don't have any specific knowledge, but that doesn't make a lot of sense to me from a mechanical standpoint. I mean, the anodizing process doesn't care about surface geometries, so anodizing before or after wouldn't be too much different. And having a bare aluminum-aluminum wear surface sounds like a rather poor idea to me, what with aluminum's propensity for galling and all that.
