本研究探討基材表面紋理對於7075-T6鋁合金以及AISI 1045中碳鋼基材的鈦基金屬玻璃薄膜磨潤行為之影響，分別披覆不同厚度(200nm和400nm)之鈦基金屬玻璃薄膜(Ti43Zr15Cu37Nb3Co2)於不同基材，在冷凍油環境下進行磨耗試驗，藉以評估表面紋理，提升薄膜附著力之可行性。此外，利用X射線光電子能譜儀(XPS)觀察各種金屬玻璃中的成分，再藉由磨耗試驗、奈米壓痕試驗以及刮痕試驗來量測薄膜之機械性質及附著強度，並利用ANSYS軟體，分析7075-T6鋁合金以及AISI 1045中碳鋼基材上披覆鈦基金屬玻璃薄膜的應力分佈，用以找出影響試片磨耗性能之關鍵因素。
磨耗試驗結果顯示，交叉紋路表面的基材披覆200nm鈦基金屬玻璃薄膜之試片具有最佳的耐磨耗能力，這是由於表面紋理能產生機械互鎖效應增加其附著能力，而金屬玻璃薄膜可以增加磨潤性能與減少磨耗之損失。
此外，基材與薄膜間之楊氏係數比值愈大，使薄膜承受的張應力相對較小，而不易破裂使耐磨耗能力較佳。

In this study, surface coating with different thickness (200 and 400nm) of Ti-based (Ti43Zr15Cu37Nb3Co2) thin film metallic glass (TFMG) were successfully deposited on the 7075 aluminum alloy and AISI 1045 medium carbon steel to the improve the tribological properties of the substrate. Wear tests were conducted in the environment with refrigerant oil to evaluate the tribological performance of the coating. In addition, the chemical composition of the specimens were identified by X-Ray photoelectron spectroscope. The wear, nanoindentation and scratch test were used to characterize wear resistance, mechanical properties and adhesion strength of thin film, respectively. ANSYS package was used to analyze the stress distribution of the Ti-based TFMG on the 7075 aluminum alloy and AISI 1045 medium carbon steel substrates, separately. The crucial factors of influence on tribological performance can thus be identified.
According to the wear test results, surface of the specimen with cross texture coated with 200nm-thickness Ti-based TFMG presented the best wear resistance properties than the other specimens for the same substrate. It is attributed that the surface texture can increase adhesion strength due to the mechanical locking effect, thereby TFMG coating can increase tribological performance.
Besides, a high ratio of the Young's modulus of the substrate and coating results low tensile stress, and thus thin film was not easy to crack presenting the better wear resistance.
