Abstract
To expand the applications of MXene-Ti3C2 in the field of oil lubrication, rounded groove surfaces filled with Sn-Ag-Cu-Ti3C2 on CSS-42L bearing steel (RGSs-SACT-600) were prepared. Block-on-ring friction and vibration tests under oil lubrication were carried out. The results showed that the synergistic effects of Sn-Ag-Cu-Ti3C2 and grooves improved the variation characteristics of friction forces and reduced friction and vibration on the surfaces. Sn-Ag-Cu-Ti3C2 with excellent adsorption to lubricating oil suppressed the oil film rupture and improved the heat dissipation at the friction interface. The tribochemical reactions were induced by Sn-Ag-Cu and Sn-Ag-Cu-Ti3C2, improving the tribological properties on the worn surfaces. Under low speed and high load, RGSs-SACT-600 with uniform profiles had excellent bearing capacity and antifriction performance.
