One of the most critical area on which aviation industry research is still focused relates to the construction materials for airframe structure. There are certain requirements must be met by candidates to construct the airframes, which are basically determined by primary factors such as strength, weight, and reliability. Amongst these materials, aluminum alloys due to their unique characteristics are being widely used by aircrafts manufactures. The attractiveness of aluminum relies on its moderately low cost, high strength-to-weight ratio, ease of fabrication, good stiffness and fracture toughness. On the other hand, there, similar to other construction materials, are drawbacks associated with the use of aluminum alloys; susceptibility to damage by corrosion and fatigue. This study investigate the corrosion susceptibility of the bulk aluminum alloys found in airplane structure, 2000 (Al-Cu-Mg) and 7000 (Al-Zn-Mg-Cu) series, in different pH and temperatures. In addition, the corrosion protection efficiency of zinc-phosphate and epoxy resin as primer coatings are examined by electrochemical techniques.
