- Аннотация: The electrolytes with halide anions generally act as aggressive media, causing the pitting corrosion of aluminum alloys. Among other halides, the electrolytes with an iodide anion were considered a less corrosive medium. However, recently a notable corrosive damage of aluminum alloys with the protective superhydrophobic coatings was found for samples exposed to potassium iodide solutions in outdoor conditions. In this paper we analyze the difference in the wetting behavior and in the evolution of the electrochemical parameters of Al-Mg alloys with the superhydrophobic coatings exposed to potassium iodide solutions at different illumination and temperature conditions. Basing on the experimental data, we show that in the presence of oxygen, the spontaneous oxidation of iodide with liberation of iodine provokes the processes leading to different degradation of the superhydrophobic state and corrosion resistance of the superhydrophobic coatings at the exposure conditions studied.
