高压直流干扰下X80钢在不同土壤中的腐蚀行为
Corrosion Behavior of X80 Steel in Different Soils under HVDC Interference
摘 要
考察了在黏土和砂土环境中,大幅值直流干扰下X80管线钢的腐蚀行为。结果表明:在100 V的高压直流(HVDC)干扰下,X80钢在黏土和砂土中的腐蚀速率分别为10.77 μm/h和1.27 μm/h,试样在黏土中的腐蚀速率是在砂土中的8.5倍。干扰后试样在砂土中的腐蚀程度较轻,这是因为砂土中的扩散电阻更高,试样在其中的电流密度更低。

Abstract
The corrosion behaviors in clay soil environment and sand soil environment of X80 pipeline steel with significant direct current interference were investigated respectively. The results showed that the corrosion rates of X80 steel in soil environment and sand soil environment with a high voltage direct current (HVDC) interference of 100 V were 10.77 μm/h and 1.27 μm/h, respectively. The corrosion rate of samples in clay was 8.5 times that in sand. The corrosion of the sample in sandy soil environment after interference was relatively mild, because the diffusion resistance in sand was relatively high, and the current density of the sample in it was relatively low.
