Aluminizing and Corrosion of Carbon Steels in N2/0.5%H2S Gas at 650-850℃ Abro, Muhammad Ali; Lee, Dong Bok;
The effect of hot-dip aluminizing on the corrosion of the low carbon steel was studied at for 20-50 h in gas. The aluminized steel consisted primarily of the Al topcoat and the underlying Al-Fe alloy layer. Aluminizing drastically improved the corrosion resistance by forming the surface scale. Without aluminizing, the steel formed nonadherent, fragile, thick scales, which consisted of FeS as the major phase and iron oxides such as FeO, and as minor ones.
