Development of a demonstrator for the qualification of the impact of de-icing agents on the corrosion appearance through aging tests
Résumé
This paper underlines the importance of surveillance of the corrosion appearance on infrastructure materials that are constantly exposed to corrosive products such as road salt in the winter maintenance context. A specific experimental setup and methodology for the evaluation of corrosion risks of materials in contact with salted solutions were developed. Aging tests, based on a cyclic immersion of metallic samples in corrosive solutions, were performed on aluminum, crude and galvanized steel, with an investigation of the influence of parameters such as solution concentration, sample active surface and air exposure. The results show a great influence of the solution concentration on crude steel, and the enhancement of corrosion appearance and propagation by air exposure.
