Atmosphere corrosion of steel structure is one of the most critical issues. Hot-dip coatings are of great significance in protecting steel to improve the durability of the structure and reduce their cast. Hot-dip coatings are usually used for relatively small size steel members such as bolts, etc., and the majority of the tiny parts can be coated. In this study, the galvanic corrosion behavior of 55Al-Zn and Al coatings in an atmospheric environment was investigated according to the exposure test and electrochemical test.
