Alkaline Anodizing of Titanium


We want to anodize Ti-6Al-4V in alkali solution as per AMS 2488 [link by ed. to spec at TechStreet] type 2 having pH 12. Kindly give details regarding voltage, current density, time and details of pre/post treatments required. Any help in regard will be appreciated.

Hi, Sreenivasan. I'm afraid that this may be one of those unusual cases where, despite the fact that there is an AMS spec for the process, the details of the process are known by only a handful of companies and held as trade secret. Sorry, but I don't think anyone is going to print a proven process for AMS 2488 [link by ed. to spec at TechStreet]. Unless you retain a consultant who is experienced in it, I think that all you can do is obey the requirements of the spec, and figure out the rest through trial and error. Good luck.
