- Abstract
The corrosion behaviours of original X80 steel, normalized, quenched and tempered X80 steel in Yingtan and Korla simulative soil solution were studied by weight loss. The polarization curve of original X80 steel in two simulative soil solution was measured. The result of weight loss shows that the corrosion rates of X80 steel samples with different metallographic structure decreases firstly and then tend to steady with time passed by. The peak corrosion rate of these samples takes place in early corrosion stage. The corrosion rate of X80 steel in Yingtan simulative soil solution is lower than that in Korla's. The original X80 steel occurs active dissolve in both of Yingtan and Korla simulative soil solution via the polarization curves. The corrosion rate of X80 steel in Korla simulative soil solution is high due to the more negative corrosion potential and larger corrosion current.
