This study seeks to address a problem of interest of ALMAHO Inc., a Canadian company situated at Levis, Quebec that specializes in industrial anodization of metals. ALMAHO Inc. seeks our expertise in the understanding of the kinetics of anodization process of aluminum alloys and aluminum metal matrix composites (MMCs). Anodization of aluminum is commonly done in an acid bath using an electric field. The structure of the anodized surface depends on the composition of the alloys, bath temperatures, acid concentrations etc. The anodization process can get more complex when it comes to anodizing the metal matrix composites (MMC)) due to the poor-reactive properties of ceramics with acids. Therefore, in this project, the kinetic models will be developed on the anodization process using a standard aluminum alloy (A6061) as well as on B4C ceramic micro-particles incorporated aluminum as MMC. The experimental results of the anodized pore sizes, pore densities and pore lengths obtained using different anodization parameters will be incorporated in these models.
