Abstract
Key parts of steel structure in a coastal power plant are coated with multilayer petrolatum coating. Salt spray test and electrochemical impedance spectroscopy (EIS) technology were used to study the anti-corrosion ability of anti-corrosion petrolatum grease and anti-corrosion tape. Applications of multilayer petrolatum coated anti-corrosion system were discussed, and the process of the technology was also introduced. The results of salt spray test and EIS showed that the anti-corrosion petrolatum grease and anti-corrosion tape had high obstructive capacity for H2O, O2 and Cl-. The results of this project also illuminate that multilayer petrolatum coated anti-corrosion system is a reliable and advanced technology.
