用稳态极化法 ,阳极动电位扫描法研究了给定酸度而不同H2 S浓度和给定H2 S浓度而不同酸度的溶液中H2 S对N80号油管钢腐蚀行为的影响 .结果表明 :酸性溶液中H2 S会吸附在油管钢表面从而促进腐蚀反应阳极过程的进行 ,且随着溶液中H2 S浓度的增大油管钢耐蚀能力降低 ,腐蚀速率加快
The steady-state polarization method and anodic potential scan method were used to study the effect of H2S on the corrosion behavior of tubing N80 at a given acidity but different H2S concentration and given H2S concentration but different acidity.The results showed that the acidity H2S in the solution will adsorb on the surface of the tubing to promote the progress of the corrosion reaction. With the increase of H2S concentration in the solution, the corrosion resistance of the tubing will be reduced and the corrosion rate will be accelerated
