这项研究试图解决位于利维斯的加拿大公司ALMAHO Inc.感兴趣的问题， 专门从事金属工业阳极氧化的魁北克。ALMAHO Inc.寻求我们在 对铝合金及铝基阳极氧化过程动力学的认识 复合材料(MMC)。铝阳极氧化通常是在酸性溶液中使用电场进行的。这个 阳极氧化表面的结构取决于合金的组成、镀液温度、酸度 浓度等。当涉及到金属基质的阳极氧化时，阳极氧化过程可能会变得更加复杂 复合材料(MMC)是由于陶瓷与酸的反应性能较差造成的。因此，在这个项目中， 此外，还将使用标准铝合金(A6061)建立阳极氧化过程的动力学模型 在B4C陶瓷上，掺入铝的微粒作为金属基复合材料。阳极氧化的实验结果 使用不同的阳极氧化参数获得的孔大小、孔密度和孔长度将被合并 在这些模型中。

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.
