-
Abstract
The EIS characteristics of an anodic type anticorrosion coating prepared with Al-Mg alloy were studied.Through fitting and analyzing the Nyquist graphs,the characteristic equivalent circuit was put forward,the relationship between the change of EIS and film property was discussed.The effect mechanism of Al-Mg alloy anodic pigment was theoretically deduced.
