Abstract

A matrix of different anodized aluminum formulations was characterized using FESEM imaging to determine structural features and TGA to examine the moisture outgassing behavior. Formulations that included a boil sealing step produced a capped structure. Formulations that included an advanced sealing step did not produce this structure and exhibited protracted outgassing responses. A numerical model was developed based on the uncapped structure. The model incorporates structural measurements derived from imaging, and allows calculation of fundamental kinetic and thermodynamic parameters of the film by fitting the predicted outgassing behavior to the experimental data.
