| Abstract: |
| Objective To explore the protective performance of organic coatings in allusion to the phenomenon that vehicle equipment used in the harsh climate and environment, such as high salt fog, hot and humid, solar radiation, for a long time will be influenced by corrosion. Methods The electrochemical impedance spectroscopy technology was adopted to research corrosion electrochemical behaviors of army green organic coating and metallic paint organic coating in 3.5% NaCl solution and analyzeelectrochemical impedance characteristics of these two kinds of coating during soaking. Coating resistance Rc and coating capacitance Cc were obtained by fitting the equivalent circuit. And the two electrochemical parameters were used to evaluate corrosion resistance of army green organic coating and metal paint coating. Results The army green organic coating had very strong ability to resistance corrosion medium penetration, and metallic paint organic coating’s ability was a bit weak. Conclusion Both coatings showed good protective performance, and metallic paint coating is superior to the tarmac organic coating during the later corrosion period. |
