开展了碳钢交流电腐蚀失重试验及交流干扰下极化曲线测量，结果表明，在研究的交流电流密度0~250A／m2范围内，碳钢交流电腐蚀速度与干扰强度符合幂函数方程。交流干扰对极化曲线的影响表现为降低了表面反应电阻Rp，及降低阴、阳极Tafel斜率。由此解释了交流电腐蚀特征与规律，并探讨了交流电腐蚀机理。“,”Mass loss tests were performed for carbon steel corrosion induced by alternating current, as well as the measurement of polarization curves under AC interference. The results show that the AC corrosion rate of carbon steel follows a power function with th
