1. Introduction
The aluminium alloy 2024 properties, such as high strength-to-weight ratio, good fracture toughness and low cost, have
maintained its dominant position in aerospace industry [1]. This kind of aluminium alloy has a complex distribution and
composition of intermetallic particles. It is well known that corrosion process initiate in intermetallic particles, specifically
in the S-phase with preferential dissolution of Al and Mg [2,3]. The localized corrosion constitutes the main degradation form of this alloy [2,4,5]. According to some authors the formation of stable pits evolves the cooperative mechanism, by galvanic coupling of intermetallic particles [6]. The cooperative corrosion process comprise the appearance and development of corrosion
