本研究旨在利用複合式脈衝陽極氧化（Hybrid Pulse Anodization, HPA）製程技術，在室溫下以0.3 M濃度的草酸處理商用鋁合金基板AA5052，調節不同的電壓參數和陽極時間，製備奈米多孔型陽極氧化鋁模板。同時，通過濺鍍技術在其表面沉積不同種類以及不同厚度的金屬，以增強結構色彩的飽和度，並且探討MDM結構與薄膜干涉機制對於結構色彩及反射光譜的影響。本研究還觀察了陽極氧化成長速率和孔洞形貌，並研究了控制不同實驗參數對於陽極氧化鋁結構色彩的影響。
使用光學量測技術在可見光範圍（350~800 nm）內建立了陽極氧化時間與色譜波長之間的關係，以獲得陽極氧化鋁結構色彩的特性，也結合觀察到的陽極氧化成長速率和布拉格繞射公式，驗證了陽極氧化鋁的著色原理，我們進一步推導出厚度與時間的關係，可應用於製備紫、藍、綠、黃、橘等不同色彩的陽極氧化鋁結構。並且成功地在商用鋁合金上實現了多種色彩在CIE1931色度圖中進行驗證，其中包括色彩分佈、色彩循環速率、個別顏色飽和度。同時，使用MDM結構開創出更多色彩可能性，搭配不同鍍層金屬和鍍層厚度，增強其顏色飽和度以及創造更多色調，這有助於未來在陽極氧化鋁圖案設計中選擇不同的顏色和圖案，並應用於不同的鋁金屬基材上。

This study aims to utilize the Hybrid Pulse Anodization (HPA) process technique to prepare nano-porous anodic aluminum oxide (AAO) templates on a commercial aluminum alloy substrate AA5052, by anodizing it with 0.3M concentration of oxalic acid at room temperature. Different voltage parameters and anodization times were adjusted to regulate the formation of the AAO templates. Additionally, various types and thicknesses of metals were deposited on the surface using sputtering techniques to enhance the saturation of structural colors and investigate the effects of the Metal-Dielectric-Metal (MDM) structure and thin film interference mechanism on structural colors and reflection spectra. The study also observed the growth rate and morphology of anodic oxide and examined the influence of different experimental parameters on the structural colors of anodic aluminum oxide.
Optical measurement techniques were employed to establish the relationship between anodization time and spectral wavelength in the visible light range (350~800 nm) to obtain the characteristics of the structural colors of anodic aluminum oxide. The coloring principle of anodic aluminum oxide was validated by combining the observed growth rate of anodic oxide and the Bragg diffraction formula. Furthermore, a relationship between thickness and time was derived, which can be applied to prepare anodic aluminum oxide structures with different colors, such as purple, blue, green, yellow, orange, etc. Multiple colors were successfully achieved on the commercial aluminum alloy and verified on the CIE1931 chromaticity diagram, including color distribution, color cycle rate, and individual color saturation. The use of the MDM structure, along with different metal coatings and coating thicknesses, expanded the possibilities for colors, enhancing color saturation and creating a wider range of hues. This opens up opportunities for selecting different colors and patterns in anodic aluminum oxide pattern design and applying them to various aluminum metal substrates in the future.
