Objective To study the corrosion failure behavior and evaluate the protection property of the coating for the corrosion critical component on transmission line iron tower, and to provide test proofs for determining the calendar life of coatings and formulating maintenance compendium. Methods The anti-corrosion properties of Zn coating, zinc rich paint/Zn, and rust coating/Zn for the transmission line iron tower were investigated by neutral salt spray test to simulate the environment of coastal area. The morphology and electrochemical properties of the coatings were evaluated by microscope, polarization curve and EIS. Results The corrosion occurred in large area of the Zn coating and zinc rich paint/Zn coating after 150 h of salt spray treatment, while no obvious corrosion was observed with rust coating/Zn after 2000 h of salt spray treatment. Conclusion The anti-corrosion performance of rust coating/Zn was superior to the other two coatings. |
