Abstract

Purpose The purpose of this study is to investigate cathodic protection (CP) efficiency in the tidal zone and its associated processes. Design/methodology/approach Specific features of CP in the tidal zone, that is, persistence of a thin seawater film and insufficient cathodic potential due to ohmic drop, were addressed. In this preliminary study, carbon steel electrodes were polarized at two cathodic potentials (correct or insufficient protection) while immersed in 1 mm or 5 mm thick natural seawater layers. After CP interruption, the protective ability of the layers covering the steel electrodes was studied using various electrochemical methods, including electrochemical impedance spectroscopy. The layers were characterized by XRD. Findings The protective ability of calcareous deposits was increased in thin seawater films. Insufficient CP could promote protective aragonite/corrosion products layer. Originality/value The combined effects of thin seawater film and applied potential were never addressed, and the conclusions drawn from this preliminary study give new insight on the efficiency of CP in the tidal zone.

碳钢在海水薄层中的阴极保护
目的研究潮汐带阴极保护(CP)的效率及其相关过程。设计/方法/方法研究了潮汐带CP的具体特征,即薄海水膜的持久性和由于欧姆降导致的阴极电势不足。在这项初步研究中,碳钢电极在浸入1 mm或5 mm厚的天然海水层。CP中断后,使用包括电化学阻抗谱在内的各种电化学方法研究了覆盖钢电极的层的保护能力。用XRD对这些层进行了表征。发现薄海水膜对钙质沉积物的保护能力增强。CP不足可能会促进文石/腐蚀产物的保护层。原创性/价值薄海水膜和应用潜力的综合效应从未得到解决,这项初步研究得出的结论为CP在潮汐带的效率提供了新的见解。

期刊介绍: Anti-Corrosion Methods and Materials publishes a broad coverage of the materials and techniques employed in corrosion prevention. Coverage is essentially of a practical nature and designed to be of material benefit to those working in the field. Proven applications are covered together with company news and new product information. Anti-Corrosion Methods and Materials now also includes research articles that reflect the most interesting and strategically important research and development activities from around the world. Every year, industry pays a massive and rising cost for its corrosion problems. Research and development into new materials, processes and initiatives to combat this loss is increasing, and new findings are constantly coming to light which can help to beat corrosion problems throughout industry. This journal uniquely focuses on these exciting developments to make essential reading for anyone aiming to regain profits lost through corrosion difficulties. • New methods, materials and software • New developments in research and industry • Stainless steels • Protection of structural steelwork • Industry update, conference news, dates and events • Environmental issues • Health & safety, including EC regulations • Corrosion monitoring and plant health assessment • The latest equipment and processes • Corrosion cost and corrosion risk management.
