However, the prolonged running-in period and low bearing capacity have limited its widespread application. In this study, we determined that the running-in period can be decreased by more than 75% when the pH value of the lubricant is controlled at 3 by introducing various acid solutions. Additionally, less time was required to realize stable superlubricity with inorganic acid at lower pH values. This was mainly attributed to the acceleration effect of hydrogen ions around the contact region. In case of PAG aqueous solution with organic acid, the wear loss between sliding solid surfaces was reduced, and thus the bearing pressure during the superlubricity period was significantly improved from approximately 30 to 160 MPa. 2023-04-14T07:07:28Z 2023-04-14T07:07:28Z 2022 Book https://link.springer.com/article/10.1007/s40544-022-0626-5 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7942 en application/pdf Springer |
