摘要

本研究的目標是探討表面織構對摩擦性能的影響，表面織構是指藉由一定的加工手段在表面製備出具有一定尺寸和排列的凹坑、凹痕或凸包等圖案，以提高其摩擦性能的一種方法。
本研究針對改變織構參數，探討對摩擦性能的影響，透過模擬分析結果和實驗結果進行比對。模擬分析以雷諾方程式為基礎，使用改進的快速數值演算法。而在分析驗證方面，藉由Pin-on-Disk磨潤實驗得到摩擦係數，針對不同表面織構分佈密度、織構大小進行磨潤實驗，對織構參數進行比較，可了解表面織構對摩擦係數的影響。
同時在試片製備方面，採用蝕刻製程加工表面織構，探討光阻塗層、曝光量和蝕刻時間，對織構加工品質的影響，找出關鍵操作參數以利於表面織構於未來機械零組件的運用。實驗結果顯示，施加表面織構確實能降低摩擦係數，密度比越低摩擦係數越小，間距越大摩擦係數越小。實驗結果顯示，密度比越低摩擦係數越小。

This study aims to explore the effect of surface texture on performance of friction. Surface texture is a method of increase performance of friction by manufacturing on the surface of stainless steel to make specific size and arrangement of patterns, such as pits, dents and convex hull.
We changed the parameters of texture to explore the effect of surface texture on performance of friction, compared the simulation with experimental results. The simulation analysis is based on the Reynolds equation and the improved sub-structure finite element algorithms. In order to verify the simulation result, we got the coefficient of friction from Pin-on-Disk wear test, implemented the experiments of using different density of surface texture and texture size and compared with parameters of texture. According the results we can understand the effect of surface texture on friction.
In sampling part, we compared the quality of different photoresist coating, exposure and etching time to identify the key operating parameters. The results showed surface texture reduce the friction coefficient. The smaller the density is, the smaller coefficient of friction will be; the bigger the distance is, the smaller the coefficient of friction will be.
