Paul,
in this case I think it just means a 'case hardened' coating on the
(usually) aluminium parts we machine up.

Alum is so soft it's easily scratched, anodising protects the outer
face.
You notice this when you try and do a lathe cut on some anodised
aluminium and it's lots harder than the soft aluminium underneath.
Frustrating too, because the anodising sometimes blunts your lathe
tool
