摘　　要：通过霉菌实验,研究霉菌侵蚀对醇酸树脂涂层外观和性能的影响规律以及百菌清(TPN)的加入对霉变的抑制作用。采用体式显微镜观察涂层长霉情况。扫描电子显微镜、原子力显微镜观察去除霉菌后涂层微观形貌。电化学交流阻抗谱法(EIS)研究霉菌实验后涂层耐蚀性变化。测试结果显示随霉菌实验时间增加,涂层微观表面粗糙度、起伏度增大,霉菌生长厚重区域有坑蚀产生,涂层耐蚀性下降。The impact of mold erosion on the appearance and performance of alkyd resin coating used in aviation and the inhibition of fungicide （chlorothalonil, TPN）added to the coatings were studied through mold test. The mildew situation of coatings were observed by using stereo microscope. The morphology of the coatings removal of mold were investigated by using scanning electron microscopy （SEM） and atomic force microscope（AFM）. The change of corrosion resistance of the coatings were studied by electrochemical impedance spectroscopy （EIS）. The results demonstrated that mildew situation is related to mold test time and the amount of TPN. With the mold test time increased, The roughness and the undulation of the coating microscopic surface in- creased, the pit corrosion generated in the thick region of the mold growth. Corrosion resistance of coating dropped significantly.
