Brication mechanism of the IL [N1888] [NTf2] inside a steel-to-steel get in touch with had been investigated by performing the wear tests around the MTM tribotester. The morphology and chemical components on worm surfaces have been analyzed by the optical microscope and SEM/EDX. In the obtained final results, the lubrication mechanisms in the oxide nanoparticles in IL, includingMaterials 2021, 14,13 ofrolling, mending, and tribofilms’ formation of nanoparticles around the make contact with surfaces are discussed in detail to explain the reduction in friction coefficient and put on. The conclusions in the present study are summarized as follows: (1) (two) In the exact same concentrations of 0.2 and 0.five wt , the ZnO nanoparticles enhanced the tribological behavior of IL improved than the CuO nanoparticles. Compared to the test lubricated using the IL, the addition of both oxide nanoparticles within the IL could decrease the friction coefficient by roughly two.four to three.5 according to their concentrations. On the other hand, the wear width was decreased by four.6 to 32 in the experiments with ZnO, while it was elevated by 8.six to 23.7 in the experiments with CuO. Hence, ZnO nanoparticles in the IL show a far better result in minimizing wear width than the CuO nanoparticles. This behavior could possibly be connected to the fact that CuO nanoparticles have a reduced bulk hardness than ZnO and are as a result additional probably to become Charybdotoxin In Vivo deposited and flattened in the get in touch with region, resulting in a larger interface for friction [34]. From the EDX evaluation benefits, it might be observed that the lubrication mechanisms of CuO and ZnO, when used as additives within the IL, are tribo-sintering and third body with pure rolling mechanisms, respectively. Out of your two sorts of nanoparticles and two concentrations tested, the ideal tribological performance was observed in the concentration of 0.two wt ZnO.(three)(4)Author Contributions: Conceptualization, J.-H.H. and T.-N.T.; methodology, J.-H.H. and S.-Y.C.; validation, J.-H.H. and T.-N.T.; formal evaluation, T.-N.T.; investigation, T.-N.T. and S.-Y.C.; sources, J.-H.H.; information curation, T.-N.T.; writing–original draft preparation, T.-N.T.; writing–review and editing, J.-H.H. and S.-Y.C.; visualization, T.-N.T. and S.-Y.C.; supervision, J.-H.H.; project administration, J.-H.H.; funding acquisition, J.-H.H.
