Application of Laser Raman Spectroscopy to the Corrosion Study

Abstract

The laser Raman spectroscopy was reviewed on its application to the study of metallic corrosion. The laser Raman spectroscopy may be one of the promising methods to dectect the compositions of corrosion films on metals under in-situ conditions. The following examples of measurements have been introduced: (1) Assignment of iron rust, (2) In-situ measurement of the oxide layer thermally formed in gaseous environments, (3) In-situ measurement of the oxide layer anodically formed in aqueous solution, and (4) Surface-enhanced-Raman-scattering (SERS) spectra of BTA inhibitor adsorbed on cupper.
