摘　　要：涂层体系是保护舰载航空电子外置设备的有效直接方式。本文在实验室内采用模拟飞机服役环境的仿真加速腐蚀试验环境谱开展某新型涂层试件加速腐蚀试验,通过宏观观测描述试件外观形态变化,通过电化学阻抗谱分析技术,根据电化学基本特性容抗、阻抗参数,对涂层腐蚀规律和耐蚀性进行分析,研究发现,电泳涂层在4年服役期内具有一定防护性能,之后防护性能锐减。The coating system is an effective and direct way to protect the external interference equipment of avionics.In this paper,a new type of coating system accelerated corrosion experiment is carried out by using the simulated accelerated corrosion test environment spectrum of simulated aircraft service environment in the laboratory,the appearance and shape change of test piece is described by macroscopic observation,the corrosion law and corrosion resistance of coatings are analyzed by electrochemical impedance spectroscopy and capacitance parameters of coatings with resistance.It was found that the protective performance of electrophoretic caoting decreased sharply after 4 years of service.
