I'm still experimenting with this:thinking:
Most of the literature suggests that Ti-on-Ti sliding contact is more prone to galling than any other metal. The best solution, according to many different articles, is to coat one Ti surface so there is no Ti-Ti contact. A few specialty coating companies offer engineered anodizing, as opposed to color anodizing. Engineered anodizing provides a thick film (around .001") that can be used as is, or that can form a base for solid film lubricant.
Why haven't my lights been sent for anodizing? The colors of the engineered anodizing are ... not the most attractive in the world. Color #1 is called [FONT=Arial, Helvetica, sans-serif]Lustreless Gray, while color #2 is called [/FONT][FONT=Arial, Helvetica, sans-serif]Brown (Fluffy) Oxide. IMO, neither one has a great deal of eye appeal.
Color 1 meets [/FONT][FONT=Arial, Helvetica, sans-serif]AMS2488, Type II, specifications.
Color 2 meets [/FONT][FONT=Arial, Helvetica, sans-serif]AMS2487 specs.[/FONT]
