摘要

探討油酸（oleic acid）表面修飾鋁奈米粉體添加至石蠟基礎油的分散與磨潤特性，應用田口品質設計法獲得分散之最佳參數，並使用分光光度儀測量表面修飾後鋁奈米粉體在石蠟基礎油中的分散穩定性，其以田口法優化。利用Ball on Ring式磨耗試驗機測試磨耗特性，結果顯示只需低濃度的鋁奈米粉體添加至石蠟基礎油，即可獲得較純石蠟基礎油更佳的抗磨耗特性，經由電子顯微鏡（SEM）及能量光譜分析儀（EDS）分析，在磨擦表面可發現鋁奈米粉體薄膜，此薄膜不但增加了荷重承載能力也隔離兩摩擦表面，因此降低磨耗與摩擦係數。

The dispersion and tribological properties of liquid paraffin with added aluminum nanoparticles were studied in this study, this lubricant are prepared by the surface-modification method that uses oleic acid (OA). The dispersion stability of aluminum nanoparticles in liquid paraffin are measured by spectrophotometry, which can be optimization by Taguchi method. The tribological properties are evaluated by using a ball-on-ring wear tester. The results show that few concentrations of aluminum nanoparticles as additives in liquid paraffin have better antiwear and antifriction properties than the pure paraffin oil. According to the SEM and EDS analyses, the thin film on the rubbing surfaces can be formed by these aluminum nanoparticles, which not only bear the load but also separate the both interfaces, thus the wear and friction can be reduced.
