Q. Can Titanium Grade 2, ASTM B348 Bar be anodized? If so what is the industry name & standard that it is performed to?

A. A spec for alkaline anodizing of titanium is AMS 2488, Andrew. Titanium is alkaline anodized for anti-galling treatment and other engineering purposes, but it is also anodized in mild acids as a decorative finish (the titanium oxide is transparent and applied to a partial wavelength thickness, which creates interference coloration in the various ROY G BIV colors.

Hi Sharon. Please see letter 9366, which seems to suggest that AMS 2488 is applicable for structural adhesion.
