Previous research revealed the aggressivness of the marine-tropical environment on airframes. Such structures, improperly coated with protective treatments, were deteriorated by corrosion in just a matter of weeks. In addition, the amount of existing salt deposition and lack of anticorrosion maintenance programs adapted to these conditions contributed to the progressive deterioration of the aircraft. The annual costs because the corrosion were still high. Additionally, commercial aircrafts in the market have as many corrosion-related problems as those from 2 or 3 decades ago. Several studies reveal the aeronautic aluminium alloys susceptible to pitting corrosion, exfoliation corrosion, stress-corrosion cracking, intergranular corrosion, and hydrogen embrittlement in a marine-tropical environment. The most affected areas found in the aircrafts were internal and external wing structures, followed by fuselage bilge areas and flight control surfaces. Results of studies made on aeronautical aluminium alloys 2024-T3, 7075-T6, 7020, and 8090 in atmospheres containing ions Cl(-), SO3, and polluting dust have established external parameters that influence corrosion, including environmental contamination, temperature, and electrode potential. Internal parameters include alloy composition, thermal treatment, and surface coatings. Correlation of electrochemical tests, and microstructural and atmospheric tests allow a better understanding of the corrosive phenomenon in airframes, establishing criteria for material selection and preventive maintenance programs to guarantee the safe operation of the aircraft.
