| 中文摘要: |
| 目的 探究碳纤维复合材料在舰船应用时与金属材料的电偶腐蚀问题。方法 针对一种典型舰船用碳纤维增强乙烯基树脂复合材料，在青岛海洋大气环境下开展0.5、1、1.5、2 a期的自然曝晒试验，进而采用电化学分析手段考察其与低合金钢的电偶腐蚀效应，结合老化机制探究碳纤维复合材料的老化行为对其与钢电偶腐蚀的影响。结果及结论 在青岛大气环境曝晒不同周期的复合材料试样，开路电位与低合金钢相差较大，存在较高的电偶腐蚀倾向。随曝晒时间的延长，复合材料表面微裂纹不断产生、扩展，导致电化学反应活性点增多，两者电偶电流密度随之增大。在青岛海洋大气环境下暴露2 a后，碳纤维增强乙烯基树脂复合材料与低合金钢的电偶电流为0.356 9 μA/cm2，两者的电偶腐蚀敏感性达到B级。 |

| The work aims to investigate the galvanic corrosion problem faced by the combined application of carbon fiber reinforced composites with metal materials in the shipbuilding industry. A kind of typical carbon fiber reinforced vinyl resin composite was chosen as the research object and the natural exposure test was carried out in the marine atmospheric environment of Qingdao for 0.5 a, 1 a, 1.5 a and 2 a. Then, the galvanic corrosion effect of the carbon fiber reinforced composite and low alloy steel was studied by electrochemical analysis methods. Furthermore, the effect of aging behavior of the carbon fiber reinforced composite on their galvanic corrosion to steel was investigated based on aging mechanism analysis. The open circuit potentials of the composite samples exposed for different periods in the atmospheric environment of Qingdao were significantly different from that of low alloy steel, indicating a high tendency for galvanic corrosion. With the prolongation of exposure time, micro-cracks on the surface of the composite samples continued to generate and expand, leading to an increase in the active points of electrochemical reactions. As a result, the galvanic current increased accordingly. After exposure for 2 a in the marine atmospheric environment of Qingdao, the galvanic current between the carbon fiber reinforced composites and low alloy steel is 0.356 9 μA/cm2, reaching Class B for the galvanic corrosion sensitivity. |
