First-Step Anodization of Commercial Aluminium in Oxalic Acid: Role of Anodization Voltage in Tailoring the Structural Features of Porous Alumina Film and Aluminium Substrate

International Journal of Electrochemical Science, 2019
Commercially pure Al specimens were anodized in 0.3 M oxalic acid at 0 °C for 15 min using five different anodization voltages in the range 10 – 50 V. Current versus time transient plots for each anodization voltage were recorded via computer interfaced ...
