【 摘 要 】

It is highly vital in automotive body, high-speed rail overhead line parts, and water distribution systems to use hot-dip galvanized steel (HDGS) coatings for efficiency and ease of synthesis. Various novel coating systems could surpass the technical restrictions of traditional anticorrosion techniques. Because of this, inorganic or organic coating systems must be chosen accurately and suitably. Meanwhile, these coating systems should be evaluated in accordance with their unique material characteristics and synergistic electrochemical parameters. From this view, we summarize an overview of recent developments of anticorrosive coating systems research for HDGS. First, we demonstrate the traditional protective coatings to match the use of HDGS. Likewise, emerging and state-of-the-art protective coatings are summarized. Then, methods for the assessment criteria of traditional and emerging protective coatings are displayed and illustrated through electrochemical analysis. For the conclusion, we make a proposal about the future developments of protective coating systems for HDGS.
