Abstract

Most of the currently available corrosion product characterization techniques require extensive samples preparation methods and cannot be employed under aqueous conditions. Raman spectroscopy possesses the advantage of characterization of the corrosion products under practical operation conditions, including aqueous, without any sample preparation procedures. The present study examines the corrosion characteristics of AISI-4340 steel at aqueous and atmospheric environments using Raman spectroscopy. FeO, Fe2O3, and Fe3O4 were observed as the main corrosion products. The measured oxides thicknesses ratio were compared to the theoretic value obtained from Tammann equation.
