采用电化学技术和表面分析方法，研究了弹性应力和交流电流对X80管线钢在模拟土壤溶液中腐蚀行为的影响。在应力和交流的协同作用下，腐蚀电流密度为40.5 μA/cm2，约为无应力和交流时腐蚀电流密度的5倍。在交流电流作用下，钢片的腐蚀形态为点蚀，在应力和交流电流作用下，钢片由点蚀变为护城河腐蚀。通过增加铁的阳极溶解和腐蚀产物膜的孔隙率，提高了钢片的腐蚀性能。
Abstract Effects of elastic stress and alternating current (AC) on corrosion behavior of X80 pipeline steel were investigated in a simulated soil solution by electrochemical techniques and surface analysis. Corrosion current density was 40.5 μA/cm2 by synergistic effects of the stress and the AC current, being about five times of that without the stress and the AC current. Corrosion morphology of the steel coupon was pitting corrosion with application of AC current, and changed from pitting corrosion to moat corrosion under effects of the stress and the AC current. Corrosion of the steel coupon was enhanced by increasing anodic dissolution of iron and porosity of corrosion product film.
