摘　　要：液相锌的流动性不仅直接影响合金的铸造性能,而且还对热浸锌镀层厚度控制有着十分重要的意义。在液相锌中加入各种微量的合金元素可以提高流动性,从而改善热浸锌镀层的镀覆效果和表面质量,也能提高液相锌的压铸填充性能。为此,主要综述了用于热浸锌的常见合金元素(Pb、Bi、Sn、Sb、Al、Mg、RE、Ni)以及部分用于压铸锌合金的合金元素(Al、Mg)对液相锌流动性的影响。The fluidity of liquid-phase zinc not only directly influences the casting properties of the alloy but also has a very important signifi-cance for the control of hot-dip galvanized coating thickness.The addition of various trace alloying elements to liquid-phase zinc can improve the fluidity,hence improving the coating effectiveness and surface quality of hot-dip zinc coatings,as well as improving the die-casting filling properties of liquid-phase zinc.In this paper,the influences of common alloying elements(Pb,Bi,Sn,Sb,Al,Mg,RE,Ni)used in hot-dip zinc and some alloying elements(Al,Mg)used in die-cast zinc alloys on liquid-phase zinc fluidity were reviewed.
