However, their operation in harsh marine environments exposes them to risks of material degradation and structural failure, with seawater corrosion and welding-induced weaknesses being the primary concerns. This review aims to analyze these degradation mechanisms, focusing on the impact of corrosion, including pitting, intergranular corrosion, and stress corrosion cracking (SCC), as well as the vulnerabilities in welded joints, such as microstructural changes and residual stresses. The study systematically evaluates existing research to identify gaps and synthesize findings on the performance of aluminum alloys in maritime settings. © 2026 The Authors.
