摘    要:文中通过自行设计的管流动态模拟装置,研究了碳钢在质量分数为3.5%流动NaCl溶液中的磨损腐蚀。用重量法和极化曲线等方法,揭示了磨损腐蚀的规律及其腐蚀控制步骤,发现0~5.0m/s内随着流速的增大,磨损腐蚀速度增大,而在5.0~12.6m/s范围内腐蚀速度显著降低,超过12.6m/s时磨损腐蚀则又随流速增大而增大。动力学过程的分析验证了腐蚀协同效应中电化学因素起主要作用。

关 键 词:碳钢 氯化钠溶液 管流装置 协同效应 磨损腐蚀

Abstract:The erosion corrosion behavior of carbon steel in flowing solution of 3 5% NaCl was studied with self designed and made flow loop simulating apparatus by means of weight loss and polarization curve method. Results show that the erosion corrosion rate increases initially with increasing flow velocity, and when flow velocity is above 5 0 m/s the erosion corrosion rate decreases and anodic process presents passivated phenomena. However, erosion corrosion rate increases again when flow velocity is over 12 6 m/s. The further study show that the electrochemical factor plays a key role in the synergistic effect.
Keywords:carbon steel  NaCl solution  flow loop simulating apparatus  synergistic effect
