 Abstract aluminum-silicon alloys are becoming increasingly popular in the automotive and aerospace industries due to their low cost and tolerance for faults during production. This study investigated the use of the Vapirova FAV as a biocompatible and eco-friendly inhibitor to protect aluminum-silicon alloys from corrosion in a highly acidic environment. The results showed that FAV was effective in reducing corrosion and its adsorption was best described by the Langmuir adsorption model. Quantum chemical calculations revealed that FAV has a high affinity for the metal surface and its molecular structure and electronic properties were consistent with experimental observations. Overall, these results suggest that FAV can be used as a green corrosion inhibitor for aluminum-silicon alloys in highly acidic environments. This article was authored by M. A. D. Abb, Omnia A. A. L.
