电化学交流阻抗测量技术现已广泛应用于有机涂层的水溶液腐蚀研究.近年来,用交流阻抗法研究熔盐热腐蚀日趋活跃,可望用于现场监测高温熔融盐引起的燃烧装置如发电站锅炉、燃油设备、流化床燃烧系统及其它设备的腐蚀.但由于熔融盐温度高,体系复杂,反应速度快等特点,给合金的熔盐热腐蚀的交流阻抗研究带来一定的困难,特别是在熔盐热腐蚀的交流阻抗模型的建立及其动力学参数的解析等方面.作者曾围绕这一问题开展了一些研
Electrochemical impedance spectroscopy has been widely applied to the research of aqueous solution corrosion of organic coatings.In recent years, the study of the electrochemical corrosion of molten salt has become more and more active with the AC impedance method, which is expected to be used in on-site monitoring of combustion devices caused by high temperature molten salt such as power station Boiler, fuel equipment, fluidized bed combustion system and other equipment.But due to the high temperature of the molten salt, complicated system and fast reaction, it brings some difficulties in the study of AC impedance of molten salt hot corrosion of alloy, especially Is in the molten salt hot corrosion of the establishment of AC impedance model and analysis of its kinetic parameters, etc. The author has carried out some research on this issue
