Abstract: The disclosure is directed to treated titanium alloys comprising a titanium substrate coated with an oxidized surface coating or an oxide-interdiffused titanium substrate. By creating an oxidized surface coating or oxide-interdiffused titanium substrate at the titanium substrate surface, the resulting treated titanium alloy has a dark color (e.g., grey to black).
