© 2019 Wiley Publishing Ltd. Two corrosive media were used (3.5 wt% NaCl aqueous solution and distilled water) to examine the corrosion-fatigue behavior of AA 7075-T651, subjected to various surface modifications (wire-EDM, blasting, and anodizing). An in-situ corrosion-fatigue device was used to test the corrosion-fatigue durability. The apparatus is able to generate cyclic loads within a corrosive solution. The mechanical loading is simulated with the aid of finite element method (FEM). At both corrosive environments, a prolongation of the corrosion-fatigue life was achieved by the blasting procedure, compared with the as-machined specimens under same conditions. Anodizing had a deleterious impact in all examined cases.
