Title: Mechanical stability of heat-treated nanoporous anodic alumina subjected to repetitive mechanical deformation
Keywords: mechanical stability, nanoporous anodic alumina, heat-treated

Abstract: We report studies on the mechanical response and deformation behavior of heat-treated nanoporous anodic alumina (NAA) using a micro-balance test and experimental test equipment especially designed for this purpose. NAA samples were characterized mechanically by a three-point bending test using a micro-analytical balance. The deformation behavior was studied by repetitive mechanical bending of the NAA membranes using an electronically controlled system. The NAA structures were prepared electrochemically from Al sheet substrates using a two-step anodizing technique in oxalic acid followed by heat treatment at 700 °C in air. The morphological study of the aluminum oxide layer after the mechanical tests and mechanical deformation was conducted using scanning electron and optical microscopy, respectively. The experimental results showed that the techniques proposed are simple and accurate; they could, therefore, be combined to constitute a method for mechanical stability assessment of NAA
