The effect of H2S concentration on the corrosion behavior of carbon steel at 90 C

研究领域：碳钢腐蚀 测量方法：塔菲尔曲线和交流阻抗 The electrochemical behavior of SAE-1020 carbon steel in 0.25 M Na2SO4 solution containing different concentrations of H2S at 90 C was investigated using the methods of weight loss, electrochemical measurements, scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results showed that the corrosion rate of carbon steel increased significantly with the increase of H2S concentration.
