摘　　要：介绍了微量合金元素(铝、镍、钛、镁、硅、铅、稀土)对热浸镀锌的影响。微量元素的加入可以使镀层表面光亮且厚度减薄,同时合金晶粒得到细化,组织得以改善,从而提高了热浸镀锌层的防腐蚀性能。The influences of trace alloy elements （aluminum, nickel, titanium, magnesium, silicon, lead and rare earth） on the hot dip galvanizing were introduced. By the addition of trace elements, the coating surface is brightness and the thickness is thinned, while the grain of the alloy is refined and the microstructnre is improved, so the corrosion resistance of hot dip galvanized layer improves.
