Composition and morphology of corrosion products formed on galvanised steel exposed to a swimming pool atmosphere
Abstract This paper reports a study of the composition and morphology of the corrosion products formed on galvanised steel specimens exposed to a swimming pool atmosphere. Two thicknesses of hot dip zinc coatings were investigated measuring 1·8 and 180 µm, respectively. Specimens were analysed throughout a 12 month exposure period and a reaction sequence identified using the techniques of X-ray diffraction, X-ray photoelectron spectroscopy, and SEM/EDX. The main phases determined were: zincite (ZnO), simonkolleite (Zn5(OH)8Cl2. H2O), hydrated zinc hydroxychlorosulphate (Zn4Cl2(OH)4SO4. 5H2O), and hydrated sodium zinc hydroxychlorosulphate (NaZn4Cl(OH)6SO4. 6H2O). Amarantite (FeSO4(OH). 3H2O) was found only on the specimens with the thinner zinc coating through which iron diffusion from the bulk steel could occur.
