Why get Titanium then coat it?


Anodising isn't quite the same as coating. You still have the same outer
layer of titanium oxide, but you have dye molecules diffused within the
oxide layer, so it's coloured. It's just as hard as it was before.

AFAIK, the anodic film on Ti is so thin you get optical interference
within the film, hence the colour ?
