摘要

Abstract

The effects of ferrous ions on cathodic and anodic polarization behavior of the X60 steel in CO2 saturated salty water were studied by potentio-dynamic polarization method. The results show that the reducing current peak of cathodic polarization is affected significantly if FeCl2 is added to the salty solution of controlled pH

but not the anodic polarization. It is considered that the ferrous ions accelerate the formation of a protective ferrous carbonate film. Films formed by addition of ferrous ions and those formed by ferrous ions produced from steel corrosion have the same forming mechanism. The former can fully meet the formative condition of the film and can play the role of inhibitor.
