Electrochemical Impedance Spectroscopy Study of Nano-materials Modified Fluorocarbon Coating of Metal Surface

摘要

In this thesis, electrochemical impedance spectroscopy (EIS) testing technology and PowerSuite software fitting techniques were applied to research the antiseptic properties of fluorocarbon lacquer that were modified by nano-TiO_2, nano-SiO_2, nano-ZnO and unmodified fluorocarbon lacquer. In this experiment, we obtained coating density, electrolyte permeation rate and other information corrosion dynamics related, and evaluated the anticorrosive effect of the modified coating and unmodified coating. The experimental results show that the nano-SiO_2 modified fluorocarbon lacquer exhibits advantages in performance comparison.
