摘　　要：综述了镀锌板无铬钝化技术的发展,讨论了无机化学钝化和有机化学钝化工艺及钝化膜的成膜机理。指出为了避免六价铬对环境的污染和对人体的危害,采用低毒或无毒性钝化剂取代铬酸盐钝化,钼酸盐以及添加缓蚀剂的有机物钝化将成为镀锌层钝化的发展方向。The advances on non-chromium passivation of galvanized steel plate is reviewed, and the mechanism of film formation is discussed. In order to avoid hexavalent chromium pollution and harm towards human body, low toxic or non-toxic passivator should be employed to replace chromate passivation. Therefore, the molybdate passivation and organics passivation with corrosion inhibiting agent will become the main direction of galvanized layer passivation.
