摘　　要：在可锻铸铁热镀锌液中加入铝和稀土，含０．５％～５．０％铝的镀锌层的耐腐蚀性能大大提高，但其外观质量差，在含铝０．０５％～０．１０％的锌液中加入０．１０％的稀土，可以提高镀锌层的耐腐蚀性能，降低镀锌层的厚度。AbstractAluminum and rare earth were added into the hot dipping zincing melt. The experimental results showed that the addition of 0.5%￣5.0% Al could increase the corrosion resistance of the coating. As the aluminum content was 0.05%￣0.1%, the addition of 0.1% RE could also raise the anticorrosion ability but lower the thickness of the coating.
