合金元素的影响，故意或以其他方式，和材料加工铝的性能在表面处理和精加工过程中被认为是。因此，重点关注铜，但考虑到其他元素的添加，铝在环境温度下的氧化物生长，蚀刻或酸洗，转化涂层和阳极氧化过程中的行为，这些过程是生产适用产品的基本过程。此外，这样的工艺产生、改性或转化最初存在的空气形成的氧化铝膜。因此，随着在合金/膜和膜/环境界面处进行的现象以及在阳极或其它膜内进行的现象的知识，出现了控制纳米尺度的特征以改善性能的可能性。例如，合金元素的精心选择使得能够控制在处理表面处形成的纳米纹理，以及形成成分和形态改性的膜以及产生具有各种功能性质的纳米颗粒。
The influence of alloying elements, deliberate or otherwise, and material processing on the performance of aluminium during surface treatment and finishing are considered. Thus, with a significant focus on copper, but with consideration of other elemental additions, the behaviour of aluminium during growth of oxide at ambient temperature, etching or pickling, conversion coating and anodizing, essential processes for generation of fit-for-purpose products, is highlighted. Further, such processes generate, modify or transform the initially present air-formed alumina film. Consequently, with knowledge of the phenomena proceeding at the alloy/film and film/environment interfaces and those within anodic or other films, the possibility of controlling features of nanoscale dimensions for improved performance arises. For example, deliberate selection of alloying elements enables control of nanotextures formed at treated surfaces, and formation of compositionally and morphologically modified films as well as generation of nanoparticles with various functional properties.
