- Abstract
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.
