- Abstract
- The carbon steel formed the thick, somewhat porous, loosely adherent iron oxide scale when oxidized at 500-800oC for 15 h in air. It formed the thicker, more porous, nonadherent scale consisting of FeS plus iron oxides in Ar/1%SO2-mixed gas. It formed the much thicker, more porous, nonadherent scale consisting of FeS plus iron oxides in Ar/0.1% H2S-mixed gas. However, the aluminized carbon steel formed the thin, protective Al2O3 surface scale even in Ar/1%SO2-, and Ar/0.1%H2S-mixed gas. Aluminizing drastically improved the corrosion resistance in (O, S, H)-containing gas.
