ABSTRACT: Due to its characteristics, aluminum and its alloys have been widely used in the manufacture of high-speed rolling stock. The series 4000 (Alfa Pendular service), manufactured by Fiat Ferroviaria (current Alstom), have aluminum alloy case structure, highlighting the 6082 alloy due to its good formability, with applications at structure level [1]. In operation since 1999, they are subjected to reactive maintenance and planned maintenance. Regarding maintenance related to the corrosion protection of structures, it is of particular
importance to develop an appropriate specification and ensure that all tasks, with particular emphasis on
those associated with surface preparation and corrosion protection by painting, are performed in accordance
with improved practices to ensure longer service life. In addition to the conditions inherent to the service, the
vandalism to which the material is subjected, foreign bodies that cause mechanical damages, various
atmospheric conditions with environments of different categories of corrosivity, as well as accumulation of
water/condensates or cleaning products/graffiti removers, are factors that contribute to the degradation of
the material.
