| 从包括阴阳极、电位、偶对间距在内的材料自身因素，以及包括含氧量、温度、流动状态在内的环境因素两个方面，综述了异种结构材料电偶腐蚀的主要影响因素。探讨了目前国内外针对异种结构材料电偶腐蚀预防措施的研究现状，对比了国内外针对设计制造阶段和服役使用阶段的不同电偶腐蚀预防措施，最后指出我国在电偶腐蚀预防方面，规范、标准和措施匮乏以及存在的其他问题，并为接下来电偶腐蚀及防护技术的发展方向提出了建议，指出需要进一步研究实际结构因素对异种材料电偶腐蚀的影响机理和规律，并提出典型耦接件的腐蚀防护技术途径。 |
| 英文摘要: |
| In this paper, main factors affecting galvanic corrosion of heterogeneous structure materials were summarized from two aspects:the material's own factors, including anode and cathode, potential, pair spacing, and the environmental factors, including oxygen content, temperature and flow state. The research status of preventive measures against galvanic corrosion of heterogeneous structural materials at home and abroad was discussed. The preventive measures against galvanic couple corrosion at home and abroad were compared in stages of design, manufacture and service. Finally, it pointed out the lack of specifications, standards, and measures as well as other issues on galvanic corrosion prevention. It pointed out that it was needed to further study the influencing mechanism and rule of actual structure on galvanic corrosion of dissimilar materials, and put forward corrosion protection technology way of typical coupling joint. |
