Specs for Titanium Anodizing



(-----) 2006

Is there a more precise way to define the requirements for titanium anodizing that could be used instead of AMS 2488 [affil. link to spec at Techstreet] ? That spec is not really sufficient for control of the results of an anodizing process. Is there another standard spec or additional requirements that can be placed on a vendor to assure reliable and repeatable AMS 2488 treatment. For example, could hardness or other post-process tests be required on each lot? I am working as a consultant with a company that has received anodized titanium samples from two different coating vendors, both of whom supposedly met the AMS 2488 spec, but the wear resistance of the films from the two vendor is very different.

The AMS 2488 is purely for the aerospace wear test of a combined Titanium anodic coat and dry-film lubricant. You are absolutely correct that it has no sufficient control of the results of an anodizing process, especially for the medical implants.
