摘要
局部电化学阻抗谱技术(LEIS)是一种新型的电化学测试技术,可以通过测量有机涂层体系的局部阻抗,并在局部阻抗的变化、涂层电容的变化以及涂层的剥离程度之间建立起直接关系,弥补了传统电化学阻抗技术(EIS)只能反映所测面积整体平均信息的缺点,因而对评定有机涂层的环境失效有着重要意义。对该技术的测定原理、测定装置以及在评定有机涂层环境失效上的应用进行了介绍。
Local electrochemical impedance spectroscopy is a novel electrochemical testing technique. It can be used to test the local electrochemical impedance of organic coatings, and to build the direct relationship between local electrochemical impedance and the capacitance and the delamination of the organic coatings. So it is a very useful technique to assess the environmental failure of the organic coatings. The device and the application of the technique were introduced.
