Abstract

Purpose This study aims to evaluate the protection performance of zinc as sacrificial anode for ABS A steel in the presence of H2S under different temperatures, pH and salinities. Design/methodology/approach In this paper, weight loss measurements and electrochemical measurements are used to evaluate the corrosion degree of zinc and ABS A steel. Findings Under the conditions involved in this work, it is shown that zinc is a nice sacrificial anode with the reason of its stable potential and excellent anode current efficiency according to the relevant standard. And it is also found that the hydrogen evolution does not occur on ABS A steel specimens. The potential difference between cathode and anode is suitable; thus, it can be concluded that each steel is well protected. Originality/value To the best of the authors’ knowledge, no other study has analyzed the protection mechanism and effect of zinc as sacrificial anode in H2S-containing environments under high temperature at present.

含硫化氢环境下ABS A钢高温牺牲阳极防护性能评价

目的研究不同温度、pH和盐度条件下，锌作为牺牲阳极对ABS A钢在H2S存在下的保护性能。设计/方法/方法本文采用失重法和电化学法对锌和ABS钢的腐蚀程度进行评价。结果在实验条件下，锌具有稳定的电位和良好的阳极电流效率，是一种很好的牺牲阳极。在ABS A钢试样上不发生析氢。正极电位差适宜;因此，可以得出结论，每个钢都得到了很好的保护。原创性/价值据作者所知，目前还没有其他研究分析过锌作为牺牲阳极在高温含硫化氢环境中的保护机制和作用。

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.
