Abstract

The electrochemical corrosion behavior of 7075 aluminum alloy subjected to different artificial ageing treatments maintaining times was examined. This aluminum alloy is typically used in aerospace structural components such as the wing spars of aircrafts and maritime industry as different mechanic parts. Heat treatments applied on this kind of alloys influence considerably the material properties like corrosion resistance.
The specimens from the electrochemical corrosion point of view were investigated in aerated and recirculated seawater solution – source Mediterranean Sea. Using a scanning electron microscope the material surface was analyzed before and after electro-tests following the microstructure, modifications, pitting holes appearance and the effects of corrosion tracked through EDAX and VoltaMaster results analysis.
