| 英文摘要 | In order to further improve the corrosion resistance of the chromium-free Ti-Zr conversion coating on 2024 aluminum alloy (AA2024), a novel Ti-Zr based conversion coating on AA2024 is successfully prepared by introducing the cathodic inhibitor of benzimidazole into the Ti-Zr conversion solution. After the conversion treatment, AA2024 substrate is well covered with the porous Ti-Zr conversion coating composed of the micron-sized particles. And the Ti-Zr conversion coating mainly consists of the metallic oxide (TiO2, ZrO2, Al2O3), metallic fluoride (ZrF4 and AlF3) and C-N complex. More important is that there are no apparent corrosion products or detects could be observed during the whole 168 h NSS test, indicating the significantly excellent corrosion resistance for AA2024 with Ti-Zr conversion coating compared with other chrome-free conversion coatings. The electrochemical measurements indicate the corrosion resistance of the Ti-Zr conversion coating is not so outstanding at the initial stage, what is worth cherishing is that its anti-corrosion property is gradually improving in the following period. Therefore, the Ti-Zr conversion coating with excellent corrosion resistance might be a promising high-performance protective coating for AA2024 compared with other chrome-free conversion coating. |
