鉴于电偶腐蚀存在的广泛性、严重危害性和影响因素复杂性,本文从偶对材料特性,偶对几何因素和环境因素等方面综述了电偶腐蚀影响因素研究现状,重点评述了电偶电位、阴阳极面积比和环境温度等因素对电偶腐蚀行为的影响研究进展.在低温低溶解氧环境下电偶腐蚀特性和机理,偶对极性逆转的机理,电偶腐蚀预测模型,多金属复杂偶合体系等领域仍存在较大的研究空间和应用需求.

In view of the universality and severe destructiveness of galvanic corrosion,along with the complexity of influencing factors,the recent progress of galvanic corrosion research was reviewed in respect of influencing factors on galvanic corrosion,such as galvanic potential,cathode/anode area ratio and temperature.This article discussed the problems existing in the current researches and forecasted the future potential developments in the field of the characteristics and mechanism of galvanic corrosion in deep sea environment with low temperature and low dissolved oxygen,the mechanism of galvanic coupling reversal,practical galvanic corrosion prediction model and multi-metal coupling galvanic corrosion.
