CORROSION BEHAVIOR OF HOT-DIP 55% Al-Zn ALLOY COATING IN SALT WATER
|
Abstract:
The corrosion behaviors of hot-dip 55%Al-Zn alloy coating on steel in 3% NaCl solution were studied by fully immersion and partialy immersion in the solution and salt spray respectively. The coating microstructure and morphology after corrosion were observed. The corrosion process and mechanism of 55%Al-Zn alloy coating in salt water were illuminated. Results showed that 55%Al-Zn alloy coating was more corrosion resistant than galvanized coating, and had the same ability as galvanized coating to protect the steel.
