Abstract

The corroded surface of cold rolled steel sheet in the process of rinsing after alkali-cleaning was examined by means of X-ray Photoelectron Spectroscopy(XPS). In addition, the surface-treated cold rolled steel with 0.05wt% $Na_5P_3O_{10}$ solution for the purpose of preventing the corrosion was examined by means of XPS and the results were compared with those for the non-treated cold rolled steel. It was found that the corroded surface consists of $Fe_2O_3$, FeO and $Fe(OH)_3$ and the thickness of the oxide layer is about $1500{\AA}$. On the other hand, in the case of surface-treated cold rolled steel, the phosphate layer of $60{\AA}$ thickness was found to act as a protective film over the relatively thin Fe oxide layer.
