摘　　要：在热镀锌液中加入铝和稀土，发现含0．5％～5．0％铝的镀锌层耐蚀性能大大提高，但其外现质量较差；在含0．05％～0．1％铝的锌液中加入0．1％的稀土，可提高镀锌层的耐腐蚀性能，降低镀锌层的厚度，相应地也可降低镀锌温度。Aluminum and rare - earth were added into the hot dip galvanization melt, it was found that 0. 5 % ~5. 0 % Al can largely increase the corrosion resistance of the coating, but the surface is inferior.When the Aluminum content is 0.05 % ~ 0. 1 %, the addition of 0. 1 % rare - earth can raise the anticorrosion ability, and lower the thickness of the coating, at the same time lower the temperature of hot dip galvanization.
