Galvanic corrosion property of contacts between carbon fiber cloth materials and typical metal alloys in an aggressive environment

► Galvanic corrosion between carbon fiber and steel, Al- and Ti-alloys was studied. ► Potentiodynamic polarization and zero resistance ammeter (ZRA) tests were used. ► The steel and Al need a protective coating while Ti exhibits no corrosion problem. ► Oxide coatings on the Al alloy were deposited to address the galvanic corrosion. ► Unipolar + bipolar duplex mode offers excellent corrosion resistance to the coatings.
