Hybrid MXene coatings: unlocking synergistic lubrication properties of Ti₃C₂T_x and Nb₂CT_x MXenes for improved tribological performance.

ABSTRACT: The development of advanced solid lubricants is critical for enhancing energy efficiency and durability in mechanical systems. In this study, we investigate the tribological performance of hybrid solid lubricant coatings composed of two-dimensional titanium carbide (Ti₃C₂T_x)- and niobium carbide (Nb₂CT_x)-based MXenes. Coatings were applied via spray deposition onto AISI 304 stainless steel substrates and tested under dry sliding conditions against Al₂O₃ counterbodies. While individual MXene coatings exhibited limited friction stability, the hybrid Ti₃C₂T_x/Nb₂CT_xcoating demonstrated a significantly reduced and stable coefficient of friction (COF < 0.2) throughout the test duration.
