摘要

采用电化学方法研究了交流杂散电流密度对带剥离涂层缺陷的X80钢腐蚀行为的影响。实验结果表明,由于交流干扰的存在,X80钢的开路电位发生了负位移。负位移程度随交流杂散电流密度的增大而增大。切断交流干扰后的电位仍比切断前负。即切断交流电源后,腐蚀干扰继续存在。实验初期,受30A/m2交流杂散电流干扰时腐蚀电流密度约为未受交流干扰时腐蚀电流密度的1.4倍,受50A/m2交流杂散电流干扰时腐蚀电流密度约为未受交流干扰时腐蚀电流密度的2倍。

Study on the Influence of AC Stray Current on X80 Steel under Stripped Coating by Electrochemical Method
The effect of AC stray current density on corrosion behavior of X80 steel with stripped coating defects was studied by electrochemical method. The experimental results showed that the open circuit potential of X80 steel was shifted negatively due to the existence of AC interference. The degree of negative shift increased with the increasing of AC stray current density. And the potential after the cut of AC interference was still more negative than before. That is, the corrosion interference continued after cutting the AC power. In the initial stage of the experiment, the corrosion current density with 30A/m2 AC stray current interference was about 1.4 times of that without AC interference, while the corrosion current density with 50A/m2 AC stray current interference was about two times of that without AC interference.
