In the protection of military products, aerospace equipment, organic anticorrosive coating application is very extensive. At present, the varieties of organic coating, brand is numerous, but the same performance, service life. This is the researchers and engineers are facing problems to be solved. Electrochemical impedance spectroscopy technique as the key part of organic coating anticorrosion performance research, has been widely used. Based on the current development and application of organic coating and its corrosion failure, including the electrochemical impedance spectroscopy technique in the study of organic coating corrosion failure, on November 7 to 10, 2016 in xi 'an Yan Liang by China aviation industry group company the first aircraft design and research institute jointly the Chinese society of corrosion and protection professional committee member ? corrosion electrochemical and test method
