Abstract
This paper presents the results obtained in a study of the galvanic pr otection of steel provided by 55% Al-Zn coatings relative to zinc coat ings (Sendzimir) in the atmosphere. While 55% Al-Zn coatings exhibit a passive behaviour under low aggressive atmospheres (e.g. in rural and urban areas), they provide good anodic performance (comparable to tha t of zinc coatings) under marine atmospheres.
