Abstract

Corrosion products play a prominent role in reducing the degradation rate of materials in harsh environments. In this work, the erosion-corrosion behaviour of duplex stainless steel (UNS S32205) in mine water, was characterised using X-ray diffraction and Raman spectrometry. The tests include erosion-corrosion in mine water and erosion in cathodically protected distilled water. X-ray diffraction and Raman spectroscopy were employed to confirm the presence of hydrolysed iron sulphate, chromium oxide, and hydrated iron oxides. The corrosion products were able to explain the effects of pH and flow velocity on the duplex stainless steel performance in the mine water environment.
