| Abstract: | Ti-Zr-Ce conversion films were prepared on the surface of aluminum alloy with H2TiF6 and H2ZrF6 as main film-forming agents through adding sodium hexametaphosphate and cerium nitrate hexahydrate.The optimal film-forming formula was determined by orthogonal experiment as follows:H2TiF6(50%)2.0 mL/L,H2ZrF6(40%)1.0 mL/L,sodium hexametaphosphate 0.50 g/L,cerium nitrate hexahydrate 0.10 g/L,reaction temperature 30℃,reaction time 150 s,pH value 3.5.The Ti-Zr-Ce conversion film exhibit excellent corrosion resistance,its self-corrosion potential was-0.577 V and self-corrosion current density was 0.115μA/cm^2. |
