Identification of Corrosion Products on Fe and Cu Metals using Spectroscopic Methods

Abstract

In this study, the Fourier-transform infrared absorption and the Raman spectroscopies for analysis of corrosion products formed on the Fe and Cu metal surfaces after deposition in the chloride containing solution, were used. The obtained spectral patterns show that main constituent species of the corrosion products for Fe metal sample is lepidocrocite, while in the case of Cu surface there is formed mainly paratacamite. The obtained results confirm that application of vibrational spectroscopic methods is precise tool for identification and analysis of the corrosion products.
