阳极氧化铝的干涉着色是阳极氧化、阳极孔加宽（孔改性）、金属电沉积到改性孔中以及最终再阳极氧化（或不阳极氧化）的复杂电解过程的结果。由于这一顺序，阳极膜由四层不同光学性质和厚度的膜层组成.本研究将阳极膜中由金属沉积物和氧化物组成的部分视为单一的均匀膜层，其复反射率由金属的反射率和金属与氧化物的体积分数确定，提出了一个综合的干涉色光学模型.在这个模型中，除反射率外，影响颜色的变量是金属存款层和存款与基体铝之间的氧化物的厚度，这取决于电解条件。
Interference coloring of anodized aluminum is the result of a sophisticated electrolytic process of anodizing, anodic pore widening (pore modification), metal electrodeposition into modified pores, and final reanodizing (or not). Due to this sequence, the anodic film consists of four layers differing in optical property and thickness.This investigation was made by regarding a portion consisting of metal deposits and oxide as a single uniform layer in the anodic film with a complex reflective index specified by that of metal and the volume fraction of metal to oxide to propose a comprehensive optical model for interference color.In this model, variables affecting color other than the reflective index are thickness of both the metal deposit layer and oxide between the deposit and base aluminum, which depend on electrolysis conditions.The model was studied for several interference colors produced in different electrolyses and found to be in good agreement.
