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.

本研究旨在解决 ALMAHO Inc.（一家位于李维斯的加拿大公司）感兴趣的问题， 魁北克专门从事金属工业阳极氧化。 ALMAHO Inc. 寻求我们在以下方面的专业知识 了解铝合金和铝金属基体阳极氧化过程的动力学 复合材料（MMC）。铝的阳极氧化通常在酸浴中使用电场进行。这 阳极氧化表面的结构取决于合金的成分、镀液温度、酸 浓度等。当涉及到金属基体的阳极氧化时，阳极氧化过程可能会变得更加复杂 复合材料（MMC）），因为陶瓷与酸的反应性较差。因此，在本项目中， 还将使用标准铝合金 (A6061) 开发阳极氧化过程的动力学模型 如 B4C 陶瓷微粒掺入铝作为 MMC。阳极氧化实验结果 使用不同阳极氧化参数获得的孔径、孔密度和孔长度将被纳入 在这些模型中。
