Globe Design Rectangle Cast Iron Outdoor Corten Steel Fire Pit

The physical appearance of WS surface of the skyward (Fig. 2(a)) rust layer was light red brown, adherent, compact and more uniform, whereas the earthward (Fig. 2(b)) surface of the specimens was dark brown and uneven. Also the surface was rougher and high porous in nature with the looser rust particles in EOL; but in the SOL the surface was smoother with less porous nature. The skyward (Fig. 3(a)) and earthward (Fig. 3(b)) facing rust layers were analysed using ATR-FTIR. All the ATRFTIR spectra display the characteristic absorption peaks for water insoluble corrosion rust products namely lepidocrocite (£-FeOOH-1020 cm¹1 ), goethite (¡-FeOOH-890 and 790 cm¹1 ), (akaganeite) (¢-FeOOH-680 cm¹1 ) maghemite (£-Fe2O3-560 cm¹1 ).19) Water-soluble iron chloride and sulphate as residual concentration in the rust layers are hard to be detected.20) In all the spectra, the absorption peak Fig. 1 Topography of the location of atmospheric corrosion exposure site of Chennai, India.
