Abstract

In the marine environment, the surface of X80 steel under cathodic protection is highly prone to forming a dense calcium-magnesium deposit layer and adsorbing a large amount of Shewanella algae (S. algae), thus facing a severe risk of under-deposit microbial corrosion. This paper investigates the effect of the S. algae and calcium-magnesium deposit layer on the corrosion behavior of X80 steel. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), confocal laser scanning microscopy (CLSM), X-ray photoelectron spectroscopy analysis (XPS), and electrochemical techniques were utilized. Research findings indicate that the corrosion process was significantly reduced in the presence of S. algae compared to the calcium-magnesium deposit layer. When both coexist, they synergistically inhibit corrosion in the initial stage; however, prolonged immersion leads to the disruption of the calcium-magnesium deposit layer by S. algae’s metabolic activities, eliminating their synergistic inhibitory effect and resulting in a corrosion rate surpassing the media containing only S. algae.

希瓦氏藻和钙镁沉积层对海洋环境中X80碳钢腐蚀机理的影响

在海洋环境中，阴极保护下的X80钢表面极易形成致密的钙镁沉积层，并吸附大量的希瓦氏藻（S. algae），面临严重的沉积下微生物腐蚀风险。本文研究了藻和钙镁沉积层对X80钢腐蚀行为的影响。利用扫描电子显微镜（SEM）、能量色散光谱（EDS）、共聚焦激光扫描显微镜（CLSM）、x射线光电子能谱分析（XPS）和电化学技术。研究结果表明，与钙镁沉积层相比，藻的存在显著降低了腐蚀过程。两者共存时，在初始阶段协同抑制腐蚀；然而，长时间浸泡会导致藻的代谢活动破坏钙镁沉积层，消除了它们的协同抑制作用，导致腐蚀速度超过仅含藻的介质。

期刊介绍： Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry. The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
