| Abstract: | Chromate conversion coatings on metal surface have not only excellent corrosion-resistant properties, but also have a self-repair function. Chromate passivation process in need of environmental protection will be gradually replaced by a variety of non-toxic chromium-free passivation technology. Silicate, molybdate, rare earth conversion coatings, organic silane compound and other chromium-free passivation technology advantages and disadvantages and development status were described,and the future directions for metal surface treatment of chromium-free passivation of nontoxic were pointed out . |

| Keywords: | non-chrome passivation composite rare earth conversion coating organic silane non-toxic |
