    • Abstract
  • Silane modified nano-ZrO2 epoxy resin coating was prepared on the surface of 6061 aluminum alloy. The effect of nano-ZrO2 addition on the protective properties of silane modified nano-ZrO2 epoxy resin coating was studied by electrochemical test and corrosion test. The physical properties and protective properties of the coating under different conversion treatment processes were compared. The results showed that when the addition amount of nano- ZrO2 was 100 mg/L, the polarization resistance of silane modified nano-ZrO2 epoxy resin coating sample was 2 719 Ω· cm2, and the self-corrosion current density was 2.528×10-6 A·cm-2. Among the coatings treated by different conversion treatment processes, the average thickness of silane modified nano-ZrO2 epoxy resin coating was 55 μm, the peeling area ratio of the coating was 5%, the adhesion reached level 1, the polarization resistance was the largest, the self-corrosion current density was the smallest, and the coating protection performance was the best.
