| 英文摘要: |
| In this paper, the corrosion behavior and mechanism of several typical intermetallic compounds in liquid zinc are summarized. The reaction characteristics and interface failure modes of different structure intermetallic compounds such as Fe3Al, TiAl and Fe2B in liquid zinc are reviewed. It is suggested that a protective oxide film or corrosion-inhibited layer rapidly generated in the surface of the alloy may improve liquid zinc corrosion resistance and the spalling resistance and good adhesion performance of corrosion products by using adding Cr, Al and Si beneficial elements and forming corrosion-resistant phases as a strategy and the material design route. Besides, some future focus and developing direction for corrosion resistance to liquid zinc are proposed for the applications of hot-dip galvanizing in engineering equipment service (e.g. submerged rolls, stabilizer roll, etc.) in the paper. In addition, the static and flow condition corrosion damage of liquid zinc and the development of corrosion resistant material are suggested as the future research ideas in liquid zinc corrosion. |
