Localized Corrosion and Microstructure of the Aircraft Aluminium Alloy

Corrosion activity of the aircraft Al-Mg-Sc aluminium alloy has been studied using scanning electrochemical method. Microstructure analysis and phase composition have been determined in the present work. The reason of localized corrosion of the aluminium alloy has been established. This study promotes to understand the mechanism of the corrosion destruction of the material and to design technologies of its corrosion...
