Sample for measuring galvanic corrosion between conductive coating and protected base material and evaluation method

The invention relates to a sample for measuring galvanic corrosion between a conductive coating and a protected base material and an evaluation method; a microporous insulating layer is arranged between the conductive coating and the base material, the microporous insulating layer is made of an insulating material, and the layer comprises a microporous structure. After the microporous structure is filled with the conductive medium, the conductive coating and the surface of the base material can form an ion path, and the base material and the conductive coating are both connected with independent leads. The test sample provided by the invention can more comprehensively evaluate the galvanic corrosion condition between the conductive coating and other conductive materials. 本发明涉及一种用于测量导电涂层与被保护的基材之间电偶腐蚀的试样及评价方法，所述导电涂层与基材之间设置有微孔绝缘层，所述微孔绝缘层由绝缘材料构成，层中包含微孔结构，所述微孔结构填充导电介质后能够使所述导电涂层和基材表面形成离子通路，所述基材及导电涂层均连接有独立的引线。本发明所述的试样能够更全面地对导电涂层与其他导电材料间电偶腐蚀情况进行评价。
