Pore Distributions in Porous Anodic Aluminum Oxide (PAAO) Surfaces of Pure and Commercial Aluminum Substrates
Abstract: Porous anodic aluminum oxide (PAAO) surfaces were developed on pure aluminum (PA) and commercial aluminum (CA) substrates by anodization as a function of voltage in phosphoric acid bath at 278 K and were analyzed by scanning electron microscopy. The interpore distances were plotted in the form of frequency histograms to examine pore-ordering characteristics. Self-ordered porous structures have been obtained at 200 and 160 V for PA and CA substrates respectively …
