Abstract:

The capacitive properties on aluminum alloy coated by sol-gel are evaluated in this work. The samples were anodized in a H₂SO₄ solution for three different times (15, 20 and 30 min) and subsequently covered by a sol-gel. The capacitance of the samples was evaluated by electrochemical impedance spectroscopy (EIS). Firstly the capacitance of the anodizing samples was evaluated. The second condition was the evaluation of the anodized samples coated by sol-gel. The better capacitance results obtained in the first condition was observed in the blank samples and by the 15 min anodized samples. After the sol-gel deposition, the influence of coating on the overall capacitance was observed. Their stability during the immersion time of the evaluation was observed as well.
