A Research on the Performance of Grey Chassis Organic Coating on Vehicle Equipment

Abstract:

By adopting coating damage simulation method with electrochemical impedance spectroscopy, the influence of different damage degree K of grey chassis organic coating to its protective performance has been studied. The research found that electrochemical impedance spectroscopy could reflect the damage degree K of the coating. When K is less than or equal to 0.11, the coating still has prefect protective performance, when K is higher than or equal to 2.78, the protective performance of the coating is very low, and when K falls in between, the protective performance of the coating is just favorable; There exist a linear relationship between log (|Z|_0.1Hz) and log K, which may provide a theoretical basis to evaluate the protective performance of such kind of coatings.
