Abstract

With the rapid development of modern civilization, the development of Marine resources has become imminent, but seawater corrosion has become one of the most important factors hindering development. In order to overcome this problem, an environment-friendly physical anticorrosion scheme based on magnetic field (B) has been proposed. In this context, we investigate the effect of Lorentz force and gradient force of magnetic field on the corrosion behavior of carbon steel in seawater. The experimental results show that the gradient force of magnetic field inhibits corrosion while the Lorentz force promotes corrosion. Especially in B⊥E (corrosion electrical field) case, the Lorentz force influence on the corrosion behavior is greater than the gradient force, while in B//E case gradient force dominates. In addition, the effect mechanism of magnetic field on the corrosion behavior of carbon steel in seawater was revealed by comparison of corrosion product composition in different reaction regions and electrochemical impedance spectrum analysis, which will provide experimental basis for the application of environment-friendly Marine anticorrosion technology based on magnetic field.

洛伦兹力和梯度磁场力对碳钢海水腐蚀行为的影响

随着现代文明的快速发展，海洋资源的开发迫在眉睫，但海水腐蚀已成为阻碍发展的最重要因素之一。为了克服这一问题，提出了一种基于磁场（B）的环保物理防腐方案。在此背景下，我们研究了洛伦兹力和磁场梯度力对碳钢在海水中腐蚀行为的影响。实验结果表明，磁场梯度力抑制腐蚀，洛伦兹力促进腐蚀。特别是在BõE（腐蚀电场）情况下，洛伦兹力对腐蚀行为的影响大于梯度力，而在B//E情况下，梯度力占主导地位。此外，通过比较不同反应区域的腐蚀产物组成和电化学阻抗谱分析，揭示了磁场对碳钢在海水中腐蚀行为的影响机理，为基于磁场的环保型海洋防腐技术的应用提供了实验依据。

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.
