This shows that a deformed layer developed by rolling was more active but only exhibited superficial attack compared to a mechanically polished surface, which produced severe localised corrosion associated with the presence of hexagonal T1 particles. The rolled surface became increasingly corrosion resistant with time, but when coupled, galvanically enhanced severe localised corrosion sites developed on the surface over time.205-215closedAccesscorrosionmicrostructuretransmission electron microscopymetalsalloysscanning electron microscopysurfacesinterfacesaluminium alloyscopper alloyscorrosion protectionlithium alloysArtigo de periódico35410.1080/1478422X.2018.15589320000-0002-4987-3334https://orcid.org/0000-0002-4987-333443.84150.33
