Abstract

The effects of electrolyte temperature during anodization on the microstructure and electrical properties of the ZrO₂ coated Al foils were investigated. The specimens were prepared by coating ZrO₂sol on etched Al foils and anodization in MPD-boric acid electrolytes at 30, 60, and 90 ℃, respectively. Anodization potential was 700 V. The thickness of oxide layer anodized increased with increasing the electrolyte temperature. In contrast, the crystallization of ZrO₂and Al₂O₃ decreased at higher anodizing temperature. Compared with the specific capacitance of the sample anodized at 90 ℃, the specific capacitances of which anodized at 30 and 60 ℃ are enhanced about 12.8 % and 8.8 %, respectively. Therefore, the anodization at 30 ℃ can effectively improve the specific capacitance of the samples, and save the thermal energy during anodization.
