Obtaining Porous Structures in the Form of Parallel Plates on Aluminum Substrates

Abstract

We report how to obtain self-organized porous microstructures of Anodized Aluminum, using high purity Aluminum substrates of 1 cm2 and 0.5 mm, 0.13 mm thick. Microstructures were obtained by electrochemical attack, using a solution of NaOH and H2C2O4 at a temperature of 55 °C, 20V and attack times of 10, 20, 30, 60, 120, 180, 240 minutes. As a result, micrographs showed pores in the form of parallel sheets of aluminum oxides and hydroxides said according to the characterization tests
