Abstract

The high temperature and high pressure cell for in situ Micro-Raman spectroscopy has been developed for the investigation into the change in the chemical composition of the corrosion products and the surface morphology of steels during the corrosion at the elevated temperatures and pressures.
The developed cell was used for the analysis of the corrosion products on various Cr-bearing steels in a solution containing CO2 at elevated temperatures and pressures, and the chemical composition of the corrosion products were analysed continuously. These results demonstrate the utility of the developed cell for the investigation into the corrosion process of steels at elevated temperatures and pressures containing CO2.
