Abstract

Abstract Galvanic corrosion is a type of localized corrosion that widely exists in all kinds of metal structures and causes severe damage, jeopardising the safety and dependability of equipment. This paper reviews the mechanism of galvanic corrosion and related influencing factors, including the material characteristics and geometric factors of the metal pair and environmental factors. As a unique surface testing technique, wire beam electrode (WBE) is widely used in various corrosion research fields represented by galvanic corrosion. On this basis, the research progress of the WBE technique in the field of galvanic corrosion is mainly reviewed from three perspectives. The experiments also proved that the WBE technique can well characterize the corrosion evolution progression and investigate the polarity reversal mechanisms. Finally, it is pointed out that the urgent scientific problems to be solved in the research of galvanic corrosion include: galvanic corrosion research in a variety of special environments; the mechanism of the galvanic couple reversal caused by the change of corrosion factors; the corrosion behavior of a complex coupling system composed of multiple metal connections; the development of corrosion prediction models.

基于线束电极技术的电腐蚀研究进展与展望

电偶腐蚀是一种广泛存在于各种金属结构中的局部腐蚀，危害严重，危及设备的安全可靠性。本文综述了电偶腐蚀的机理及其影响因素，包括金属对的材料特性、几何因素和环境因素。钢丝束电极作为一种独特的表面检测技术，广泛应用于以电偶腐蚀为代表的各种腐蚀研究领域。在此基础上，主要从三个方面综述了WBE技术在电偶腐蚀领域的研究进展。实验还证明，WBE技术可以很好地表征腐蚀演变过程和研究极性反转机制。最后指出电偶腐蚀研究中亟待解决的科学问题包括:各种特殊环境下的电偶腐蚀研究;腐蚀因素变化导致电偶反转的机理;由多个金属连接组成的复杂耦合系统的腐蚀行为腐蚀预测模型的发展。

期刊介绍： Corrosion Reviews is an international bimonthly journal devoted to critical reviews and, to a lesser extent, outstanding original articles that are key to advancing the understanding and application of corrosion science and engineering in the service of society. Papers may be of a theoretical, experimental or practical nature, provided that they make a significant contribution to knowledge in the field.
