摘要

通过三维断层扫描深度剖面测量，量化了在0.4T磁场下硫酸溶液中铁电极波形表面随阳极极化时间的演变。在磁场下阳极溶解后的电极表面是不规则的，并且3D轮廓随着阳极极化时间的变化而变化。阳极溶解速率特定于电极上的几何位置，通常对极化时间和表面不规则性不敏感。

Self-sustained constant anodic dissolution rate on iron electrode under magnetic field

The evolution of the wavy surface of iron electrode with anodic polarization time in a sulfuric acid solution under 0.4T magnetic field is quantified by 3D tomographic depth profile measurements. The electrode surface after anodic dissolution under magnetic field is irregular and the 3D profile changes with the anodic polarization time. The anodic dissolution rate is specific to the geometrical location on the electrode, which is in general insensitive to the polarization time as well as the surface irregularity.

期刊介绍： CORROSION is the premier research journal featuring peer-reviewed technical articles from the world’s top researchers and provides a permanent record of progress in the science and technology of corrosion prevention and control. The scope of the journal includes the latest developments in areas of corrosion metallurgy, mechanisms, predictors, cracking (sulfide stress, stress corrosion, hydrogen-induced), passivation, and CO2 corrosion. 70+ years and over 7,100 peer-reviewed articles with advances in corrosion science and engineering have been published in CORROSION. The journal publishes seven article types – original articles, invited critical reviews, technical notes, corrosion communications fast-tracked for rapid publication, special research topic issues, research letters of yearly annual conference student poster sessions, and scientific investigations of field corrosion processes. CORROSION, the Journal of Science and Engineering, serves as an important communication platform for academics, researchers, technical libraries, and universities. Articles considered for CORROSION should have significant permanent value and should accomplish at least one of the following objectives: • Contribute awareness of corrosion phenomena, • Advance understanding of fundamental process, and/or • Further the knowledge of techniques and practices used to reduce corrosion.
