研究了用低毒性钼酸盐取代剧毒的重铬酸盐对热镀 Zn层进行钝化的工艺，探讨了钝化液组成、pH值、钝化处理温度及时间对钝化成膜及膜层耐 蚀性的影响.中性盐雾腐蚀(NSS)试验表明，采用该工艺可获得耐蚀性与低Cr钝化相当的具有 较为均匀的淡黄或浅蓝色钝化膜.
A low toxic passivation process by molybdate for gal vanized steel has been investigated for replacing the high toxic one by chromat e.Effects of bath composition，pH，treatment temperature and time on the proper ties of passivation film have been discussed.Results of Neutral Salt Spray test s show that，an uniform pale yellow or light blue passivation film with corrosio n resistance corresponding to that by chromate treatment is formed on the surfac e of galvanized steel by the molybdate treatment.
