Abstract
The low interlayer forces of 2D nanosheets as nano additives are conducive to enhancing the tribological performance of lubricating oil. In this work, ultrathin 2D Co-BDC MOFs nanosheets are successfully synthesized with ultrasonic assistance, and Ag nanoparticles are successfully loaded onto their surfaces via chemical adsorption. The Ag@Co-BDC nanocomposites are demonstrated to significantly improve the tribological performance of PAO10 base oil, leading to a 16.7% reduction in the friction coefficient and a 61.5% decrease in the wear rate. Moreover, macroscopic reaction further confirmed that the introduction of Ag@Co-BDC nano additives facilitated the tribochemical reaction during friction. This work successfully synthesized a novel lubricating additive with excellent tribology performance and provided a preliminary explanation of the mechanism of the tribochemical reaction.
