摘要

本研究擬利用旋轉式銷對盤摩擦試驗機暨量測系統，在摩擦過程中，藉由動態量測摩擦係數及表面磁場之變化，以研究鐵及鈦配對之垂直方向剛性及阻尼對摩擦磁化及磨潤性質的影響。銷使用鐵及鈦材料，盤使用鐵材料，並且以不同垂直剛性條件下及不同滑動速度下為實驗操作參數，在摩擦試驗後，並配合電子顯微鏡(SEM)觀察磨耗過程所產生之磨耗顆粒(Wear Particle)，並以光學顯微照片(OM)及表面型態輪廓儀AMBiOS(XP2)來研究鐵及鈦配對之垂直方向剛性及阻尼對摩擦磁化及磨潤性質的影響。 在一般的認知下純鈦並無磁性，但鈦磁鐵礦在地球科學領域卻為判讀地磁週期性逆轉的依據。因此探討鐵與鈦摩擦界面化合物、甚至是鈦磁鐵礦的摩擦磁化特性。藉由動態量測摩擦係數變化及表面磁場變化的方法未來具有發展成為動態監視分析鐵及鈦化合物的潛力。

由實驗結果可發現由不同垂直剛性及不同滑動速度下，會使摩擦界面產生許多複雜變化，而藉由這些變化來判斷界面間所產生的磨潤性質。

The experiments were conducted on a pin/disk friction tester with a measuring system to investigate the effects of normal stiffness and damping on frictional magnetization and tribological properties of the iron and titanium pairs. The friction coefficient and the surface magnetization were dynamic measured during the friction process. The pin was made of iron or titanium. The disk was only made of iron. Moreover, normal stiffness and sliding speed were selected as the experimental parameters. The SEM observations of the wear particles were conducted after the friction test. The OM and the AMBiOS(XP2) were also used to investigate in this study.
According to the experimental results, there were complex variations at the interfaces under different normal stiffness and sliding speeds. Therefore, the tribological properties can be clarified by the variations.
