电泳涂膜的丝状腐蚀及其抑制方法
|
摘要
通过钢铁表面的丝状腐蚀试验及电化学交流阻抗谱考察了不同的前处理方式、防锈颜料的种类及烘烤温度对电泳涂膜丝状腐蚀现象的影响。试验结果表明:进行三元磷化处理,添加1%的纽碧莱213,烘烤温度为180℃的电泳涂膜,丝状腐蚀现象最轻。
The influence of different pretreatment methods,anti-rust pigment types and baking temperature on the filamentous corrosion of electrophoretic film was discussed through filamentous corrosion experiments on the steel surface and electrochemical impedance spectroscopy. The lightest filamentous corrosion was showed when using three element phosphating technology,adding 1% Nubiola 213 in the coatings and keeping the baking temperature at 180℃.
