本研究之目的在於探討不同滑動行為對於兩種潤滑劑添加劑磨潤性能的影響，分別為磷系極壓添加劑與ZDDP抗磨耗添加劑，使用不同濃度加入至MN基礎油，在不同油溫以迴轉式與往復式之滑動模式進行磨耗試驗，利用磨疤直徑與磨耗軌跡寬度評估試驗用油之磨潤性能。另外，增長磨耗週期以驗證含添加劑混合油於長時間下是否有消耗現象。結果顯示，迴轉式磨耗試驗時，磷系添加劑能有效改善MN的耐極壓能力。ZDDP添加劑則於高溫條件效果較為顯著；但ZDDP添加劑在油溫較低時，因實驗溫度較低導致不易生成化合膜，無法有效保護表面。往復式磨耗試驗時，磷系添加劑混合油較有效改善MN的耐極壓能力。ZDDP添加劑混合油也能改善MN的耐極壓力，但濃度需達到3%以上才能有效保護效果。針對不同運動型態，迴轉式磨耗試驗由於滑動速度較高，造成攪拌效應相對較弱，容易形成飽和濃度層，使磨疤直徑變異不大；往復式磨耗試驗時，添加劑濃度都高於迴轉式磨耗試驗，才能有效降低磨耗量，原因為試片一秒鐘來會多次，攪拌效應較為強，不容易形成飽和濃度層，需仰賴整體濃度才能有較快的化合膜生長速率。其中，濃度達到臨界值以後，磨耗寬度趨於平穩，此即意味著表面存在有局部飽和濃度層。
增長磨耗週期時，使用較低濃度添加劑混合油的試片磨耗量都有明顯增加；但隨著添加劑濃度的增加試片的磨耗量均有明顯下降，此結果說明磨耗試驗過程中添加劑在基礎油中會有消耗的現象。另外，磷系添加劑會因濃度不足導致均質度下降引發更嚴重的磨耗行為。

The purpose of this study is to investigate the effect of different sliding behaviors on the grinding performance of two lubricant additives, namely phosphorus-based extreme pressure additive and ZDDP anti-wear additive. The wear test was carried out with the reciprocating sliding mode, and the wear performance of the test oil was evaluated by the diameter of the wear scar and the width of the wear track. In addition, increase the wear cycle to verify whether the additive-containing blend oil is worn out over a long period of time. The results show that in the rotary wear test, phosphorus-based additives can effectively improve the extreme pressure resistance of MN. The ZDDP additive is more effective at high temperature; however, when the oil temperature is low, the ZDDP additive is not easy to form a compound film due to the low experimental temperature, and cannot effectively protect the surface. In the reciprocating wear test, the phosphorus-based additive mixed oil can effectively improve the extreme pressure resistance of MN. ZDDP additive mixed oil can also improve the extreme pressure resistance of MN, but the concentration needs to be more than 3% to effectively protect the effect. According to different motion patterns, due to the high sliding speed of the rotary wear test, the stirring effect is relatively weak, and it is easy to form a saturated concentration layer, so that the variation in the diameter of the wear scar is not large; in the reciprocating wear test, the additive concentration is higher than that of the rotary wear test. Wear test can effectively reduce the amount of wear. The reason is that the test piece will be repeated several times in one second, and the stirring effect is relatively strong, and it is not easy to form a saturated concentration layer. Among them, after the concentration reaches the critical value, the wear width tends to be stable, which means that there is a local saturated concentration layer on the surface.
When the wear cycle is increased, the wear amount of the test piece using the mixed oil with the lower concentration additive increases significantly; but with the increase of the additive concentration, the wear amount of the test piece decreases significantly. This result shows that the additive is in the base oil during the wear test process. There will be consumption. In addition, phosphorus-based additives may cause more serious wear behavior due to a decrease in homogeneity due to insufficient concentration.
