| 目的 研究氟碳重防腐涂层在循环盐雾试验后的防护性能。方法 开展氟碳涂层的实验室循环盐雾试验，通过电化学阻抗谱、附着力、光泽、色差测试等方法对氟碳涂层的各性能进行分析表征，并使用等效电路图对电化学阻抗谱数据进行拟合，评价涂层在盐雾试验后的腐蚀保护性能。结果 循环盐雾试验1440 h后，涂层无失光、变色、粉化等现象，模值由1.42×1011 Ω.cm2下降至7.26×1010 Ω.cm2，下降幅度较小。结论 经循环盐雾试验后的氟碳涂层仍具有优异的防护性能。 |
| 英文摘要: |
| The corrosion protection behavior of fluorocarbon coating after cyclic salt spray test was investigated in this paper. The cyclic salt spray test was carried out according to GB/T 31588.1. The electrochemical impedance spectroscopy (EIS), adhesion, gloss and color difference tests were used to characterize the performance of the fluorocarbon coating. The electrochemical impedance spectroscopy data were fitted with equivalent circuit diagrams to evaluate the corrosion protection performance of the coating after salt spray test. After 1440 h of cyclic salt spray test, the coating had no tarnish, discoloration and powdering, the modulus value dropped from 1.42×1011Ω.cm2 to 7.26×1010Ω.cm2. The results indicated that the fluorocarbon coating still has excellent corrosion protection performance after the cyclic salt spray test. |
