So it appears that anodizing creates a thick anodic coating on the aluminum that is a thick enough barrier to galvanic corrosion. Also titanium and it’s alloys.
Also according to this article stainless steel shows little to no corrosion. https://www.corrosionpedia.com/2/1556/corrosion/galvanic-corrosion-of-metals-connected-to-carbon-fiber-reinforced-polymers
If I was to fix a carbon part to a motorcycle and used anodized bolts would the anodic coating just protect the bolt or also act as an insulator to the movement of electrons and protect other interconnected metallic components down stream?
