摘要

近年來奈米技術不斷的提昇，針對相關的檢測儀器也相繼推出，本次研究即利用此奈米測試系統，來針對金屬表面受到微小力量，所產生微量磨耗進行研究。
本研究針對使用兩種不同材質的金屬(銅和鈦)之奈米磨潤性質進行實驗，利用奈米測試系統(Nano Test System)量測金屬表面之奈米磨潤性質，以銷對盤(Pin-On-Disc，POD)磨耗的方式來進行奈米磨潤實驗，對工件材料施加負荷、改變轉速及旋轉半徑等實驗參數，來對金屬材料表面進行奈米磨潤之實驗分析，並且比較兩種金屬材料之磨潤型態。
我們可以進一步藉由SEM來觀察以銷對盤的方式對金屬所造成刮痕的表面，在施加微小的力量時金屬表面形貌的改變。利用實驗所得摩擦力的數值，經由EXCEL軟體將其數據繪製成曲線圖，進行比對便可知金屬材料(Cu、Ti)在無潤滑情形下，摩擦力的改變。

Following the constant promotion of nano technology in recent years, the detecting instruments of nano technology is also being appeared in succession. This research is to study the traces wear produced while receiving small strength on the metallic surface by nano test system.
This research is to experiment the metal of two kinds of different materials (copper and titanium) by using the property of nano tribology, to measure the property of nano tribology on the metal surface by using the nano test system, to use pin-on-disk on the nano tribology experiment, to load on the work materials, to change the rotational speed and the radius of rotation, to analyze the surface of metal material on the nano tribology experiment, and to compare the tribology type of two kinds of metallic materials .

We can go further to observe the change on the surface of the mark that the metal surface shape while exerting small strength on the metal caused by Pin-on-Disc (POD) with SEM. To draw data into the curve graph by EXCEL software with the numeric of frictional force on the experiment, comparing the change of the frictional force of the metal material (Cu, Ti) under un-lubricity.
