摘　　要：气相缓蚀剂作为抑制金属大气腐蚀的主要手段之一,其效果出色、经济效益高,得以广泛使用,发展气相缓蚀剂分析方法,对气相缓蚀剂的发展有着重要的指导意义。本文阐述了气相缓蚀剂的分类情况,气相缓蚀剂的特点及性能,根据其性能介绍了对应的检测方法包括:挥发性测试、腐蚀失重法、电化学测试法、表面分析法和构效关系计算等。总结了气相缓蚀剂分析方法并展望了气相缓蚀剂检测方法的发展趋势。As one of the main means to inhibit atmospheric corrosion of metal,vapor phase inhibitor is more and more widely used because of its excellent corrosion preventive effect,higher cost perfor-mance and easy to use.The development of analytical methods for vapor phase inhibitors has important guiding significance for the mechanism research and development of new vapor phase inhibitors.This pa-per introduces the classification of two kinds of vapor phase inhibitor,and describes the characteristics,such as volatility,solubility,adsorption and corrosion inhibition of vapor phase inhibitor.In order to test the different properties of vapor phase inhibitors,several analytical methods were introduced.The volatility test is measured in terms of saturated vapor pressure.Due to the advantages of simple operation and in-tuitive results,mass loss analysis is widely used in the detection of vapor phase inhibitors and to verify the accuracy of other methods.Electrochemical measurements can reveal a lot of features related to the action of vapor phase corrosion inhibitors,has become the mainstream method.Surface morphological techniques can further explore the film forming mechanism of corrosion inhibitor on metal surface.In sum,the current analysis methods of vapor phase inhibitors are summarized,and the future development trend of vapor phase inhibitor analysis methods is prospected.
