A Research on the Protective Performance of Green Organic Composite Coating on Vehicle Equipment

摘要

By adopting coating damage simulation research method with open circuit potential and electrochemical impedance spectroscopy, the influence of different damage levels of green organic composite coating to its protective performance has been studied. The research found that the variation of open circuit potential partly reflected the damage level of the coating. When K is less than or equal to 0.04‰, the coating still has favorable protective performance, while K is higher than 16‰, the protective performance of the coating is basically unavailable, but when K falls in between, the protective performance of the coating is fair good.
