To reduce wear and energy loss during the movement of miniaturized devices such as wearable devices and MEMS, and to address the inherent limitations of individual categories of solid lubricating materials, a new MXene-based composite solid lubricating material was designed. In this study, Ti₃C₂T_x@MoS₂ composites were successfully prepared via hydrothermal synthesis, with MoS₂ nanosheets grown uniformly on the surface and interval of the multilayer Ti₃C₂T_x. The composites were deposited as a solid lubricant coating on silicon substrates using a drop coating method. Tribological behavior was evaluated by ball-on-disk reciprocating and rotating tribometer, respectively. The results revealed that the friction coefficients of the multilayer Ti₃C₂T_x@MoS₂ composite coatings were reduced by 75%, 69%, and 58%, respectively, compared to the multilayer Ti₃C₂T_x, MoS₂, and their mechanical mixtures. Moreover, this study proposed the excellent wear resistance of the multilayer Ti₃C₂T_x@MoS₂ composite coatings was attributed to the synergistic lubrication of Ti₃C₂T_x and MoS₂. MoS₂ was enriched in the wear track, and the tribofilm formed during friction process played the role of friction reduction and lubrication. In comparison, the multilayer Ti₃C₂T_x had an excellent effect on the wear resistance and structural support.
