Abstract  

Nanocomposite zinc-rich epoxy coatings with four kinds of curing agents for transmissionline steel structure were prepared. The corrosion resistance of the coatings was investigated by using salt spray tests, immersion tests and electrochemical impedance spectroscopy. Results show that a coating with a curing agent, phenolic amine, exhibited optimal corrosion resistance. Because this curing agent has structure of benzene rings, the coating showed excellent resistance to chemical media.

Key words:  materials failure and protection      curing agent      electrochemical impedance spectroscopy      corrosion
