The microstructure of aluminum alloys plays a key role in their corrosion resistance. In particular, the presence of intermetallic precipitates differing in the potential from the alloy matrix induces local corrosion. The study presents the effect of native air-formed oxidation on the corrosion behavior of AA 7075 aluminum alloy. Various microscopic and spectroscopic techniques were used to examine the changes occurring in the microstructure and passive layer. Anodic Mg2Si phase undergoes oxidation, which results in magnesium hydroxide being built in the passive layer. EIS analysis revealed an improvement of electrochemical properties as a result of exposure to weather conditions.
