Description
Summary:The corrosion behavior of zinc-aluminum-magnesium (ZAM) coating in a simulated extremely cold atmosphere under dark and ultraviolet illumination (UV) was investigated. The corrosion rate both decreased first and then increased under two conditions. The inhibition effect of UV gradually weakened with corrosion proceeding and UV only changed relatively contents of corrosion products instead of compositions. The inhibition effect, which manifested on early corrosion process, mainly depended on the generation of more compact corrosion products. With prolongation of corrosion time, NaHSO3 and low temperature gradually played a leading role in latter corrosion process, and weakened the inhibition effect of UV.
