| 目的 研究有机涂层的加速老化动力学规律。方法 针对某飞机实际服役环境条件特点，编制有机涂层加速老化试验谱，开展0~9 a的当量加速老化试验。借助PARSTAT 4000电化学工作站，测试老化试验后涂层试件的电化学阻抗值。结果 得到了不同老化周期有机涂层的Bode图、等效电路、孔隙率、吸水率和电化学阻抗，表征了加速试验条件下的老化动力学规律。结论 低频阻抗|Z|0.01可以作涂层防腐蚀性能的评价指标，涂层老化过程大致可分为初期、中期和后期三个阶段，分别对应三个不同等效电路。 |

| bjective To study the accelerated aging dynamic rules of organic coating. Methods Accelerated aging testing spectrum of organic coating was prepared and equivalent accelerated aging test of 0～9a was carried out according to conditions and features of environment in which the plane will serve. The electrochemical impedance of coating specimens after aging tests was tested by virtue of the PARSTAT 4000 electrochemical workstation. Results Bode diagram, equivalent circuit, porosity, water absorption and electrochemical impedance of organic coatings with different aging period were obtained. Dynamic rules of accelerated aging test were characterized. Conclusion Low-frequency impedance |Z|0.01 can be used as index for evaluation of anti-corrosion coating. The aging process coating can be divided into three stages of early, middle and later, corresponding to three different equivalent circuits. |
