| 中文摘要: |
| 在综合国内外相关研究的基础上，对铝合金丝状腐蚀这一现象进行了描述，指出了铝合金发生丝状腐蚀的四个必要条件(高湿度、涂层缺陷、氧气及腐蚀性离子)。分析了腐蚀丝的引发和发展机理，列举了影响丝状腐蚀发展的重要因素(大气环境、基体金属、表面预处理和涂层)，总结对比了国内外常用的丝状腐蚀试验标准和研究方法(扫描开尔文探针检测法、电化学阻抗谱法、电化学仿真法以及自然环境试验法)。从环境控制、表面预处理和涂层使用等三个方面讨论了丝状腐蚀的抑制及防护措施。最后提出了尚需解决的四个问题:标准丝状腐蚀试验与实际大气腐蚀的相关性、有机涂层耐丝状腐蚀性能标准的制定、航空铝合金的丝状腐蚀研究、表面预处理方法的改进。 |

| The work aims to describe the filiform corrosion phenomenon of aluminum alloy based on relevant researches at home and abroad, points out the four necessary conditions (high humidity, coating defect, oxygen, and corrosive ions) for the occurrence of filiform corrosion. The initiation and development mechanism of the filaments was analyzed. Important factors (atmospheric environment, base metal, surface pretreatment, and coating) affecting filiform corrosion were listed. Commonly used test standards and research methods (scanning Kelvin probe detection method, electrochemical impedance spectroscopy, electrochemical simulation method, and natural environment exposure) of filiform corrosion were summarized and compared. Inhibition and protection measures of filiform corrosion were discussed from three aspects of environmental control, surface pretreatment and coating application. Finally, four problems that need to be solved were pointed out:the correlation between the standard filiform corrosion test and the actual atmospheric corrosion, the formulation of standard for the filiform corrosion resistance of organic coatings, the study on the filiform corrosion of aviation aluminum alloys, and the improvement of surface pretreatment methods. |
