Abstract:	近年來金屬玻璃(Metallic Glass，MG)的發明在工業領域中有著多項技術應用，使得金屬玻璃的發明引起了廣泛的興趣。在所有類型的MG中，鐵基金屬玻璃(Fe-based MG)具有較高的機械強度，良好的熱穩定性,強的耐腐蝕性，優異的軟磁性能和相對其他金屬玻璃基材較低的生產成本，因此是一個獨特且具有商業競爭力的材料。本研究主要以飛秒雷射(Femtosecond laser)誘導鐵基金屬玻璃，於材料表面產生週期性表面結構，藉由改變加工參數已進行一連串的表面形貌及特徵的探討，再藉由不同的表面形貌組合而成的大面積結構，分別比較討論耐腐蝕性、色彩表現及用於翻模應用的可行性，以材料的特性配合雷射加工後的結構，解決現有模具及後加工等相關問題，以減少繁複的工序。;In recent years, metallic glass (MG) has several technical applications in the industrial field, making metallic glass aroused widespread interest. Among all types of MG, Fe-based metallic glass (Fe-based MG) is a unique and commercially competitive material, which has high mechanical strength, good thermal stability, strong corrosion resistance, excellent soft magnetic properties, and cheaper cost than other metallic glass substrates. In this study, the femtosecond laser was used to induce Fe-based MG to produce sub-wavelength periodic surface structures on the surface of the material. By changing the laser machining parame-ters, a series of surface morphology and characteristics have been discussed. On the other hand, with a large-area structure composed of different surface morphologies, we compare the corrosion resistance, color performance, and feasibility of mold application, and use the characteristics of the material to match the structure after laser processing, and solve the related problems of existing molds and post-processing to reduce complicated procedures.
