Abstract

The present study has been carried out to investigate the corrosion behaviour of carbon–manganese steels in chloride environments at short exposure times. The influence of copper phosphorous microalloying on the corrosion resistance of carbon–manganese steels has been also addressed. The microalloying of copper and phosphorus in the steel has shown significant improvement in corrosion resistance, indicating greater hindrance to anodic dissolution. Laser Raman spectroscopy studies have shown the presence of different oxyhydroxides on the samples of carbon–manganese and copper phosphorous microalloyed steels. It was confirmed that the presence of predominant and adherent δ-FeOOH resulted in a slower dissolution rate for copper and phosphorous microalloyed steel.
