Thermal Stability of Porous Anodic Alumina Formed in Electrolytes with Surfactant Additives

Abstract

Thermal stability of porous anodic alumina formed in various electrolytes is discussed. The bending deflection of the samples measured was converted to thermal stress. A model of transformation of the pore morphology during the re-anodizing in the electrolyte at the voltage increased relative to the voltage of the primary anodization is proposed.
