摘　　要：论述了液态锌对材料造成腐蚀的机制,介绍了耐液态锌腐蚀的Cr-Si合金铸铁、渗硼铸铁和渗硼低碳钢等材料,尤其对多元复合硼共渗技术得到了脆性低、与基体牢固结合且组织致密的渗硼层作了系统叙述.该层与液态锌不润湿,隔断了铁与锌之间的反应,因此具有良好的耐液态锌腐蚀性能.The corrosion mechanism of liquid zinc to metal materials has been described in the paper.The cor-rosion resistance to zinc liquid of t he materials,such as alloy cast iron with Cr and Si,boronized cast iron an d boronized low carbon steel,has been introduced.The boronizing coatings with B -V -RE and B -Cr -RE compounds have a compact structure,good ductility,tight combination with matrix and low infiltration capacity in the zinc liquid.And therefore,the c oatings can prevent the reactions between iron and ...
