带涂层缺陷金属EIS研究中等效电路的设计

摘要

对电化学阻抗谱进行等效电路分析是研究涂层金属性能的主要方法之一.对于带有缺陷的涂层,由于对应腐蚀体系的复杂性及等效电路的不完善,很难设计合适的等效电路与实际研究相对应,而国内在此方面的问题更为突出.因此,从带有缺陷的涂层腐蚀体系的闭合回路的扰动电流的流径出发,对国内外等效电路的设计研究方法进行总结,提出科学的等效电路设计思路,可以帮助得到合理的等效电路,从而推动等效电路法的实用性与准确性.%The method analyzing impedance spectroscopy by electric circuits is widely used to study coating performance. However, as to a certain system of coating with defects, it is difficult to design a electric circuit fitting it, because of the complexity of the system and the imperfection of the electric circuit technology. Therefore, for the development of electric circuit technology, the present paper summarizes the design and research methods home and abroad, and proposes scientific mentality of designing for electric circuits.
