Galvanic Corrosion of Coated HY-130 Steel Coupled to 5456 Aluminum
1974
Hack, Harvey P.
Specimens of HY-130 steel were galvanically coupled to 5456-H117 aluminum in natural sea water at velocities of 0 to 30 feet per second. The steel was coated with an epoxy primer and topcoat to various degrees: fully coated, coated with defect, partially coated, and uncoated. Corrosion rates of both materials increased with increasing sea-water velocity. Corrosion of the HY-130 was reduced and that of the aluminum was increased when galvanically coupled, with the effect on the aluminum increasing with increasing amount of uncoated steel area.
