Abstract
Corrosion scales were formed on micro-alloyed steel designated as P110X and compared with API 5 L X65 in CO₂ saturated 3.5 wt% NaCl at 60 °C and pH 6.5 using Potentiostatic polarization at three different anodic potentialsfor 24 hours. The electrochemical behaviour of the corrosion scales were investigated using EIS and surface analysis techniques. The results revealed that the scales were non-protective demonstrating a decrease in film stability with increase in potential.It was generally observed that due to chemical composition and microstructuresAPI 5 L X65 exhibited better general corrosion resistance butshowed more prone to pitting corrosion than steel P110X.
