Synthesis, characterization, and tribological properties of two‐dimensional Ti3C2

We report on the preparation of two‐dimensional (2D) Ti 3 C 2 and its friction and wear properties. Laminated Ti 3 AlC 2 was synthesized by pressureless sintering using Ti, Al, and graphite, followed by HF exfoliation and sonication treatment to form 2D‐layered Ti 3 C 2 , which exhibited individual layer or stack of several layers. Analysis of microstructure and composition was used to confirm the successful exfoliation of laminated Ti 3 AlC 2 . The tribological behaviors of the as‐prepared 2D Ti 3 C 2 as a lubrication additive in base oil were investigated. Results indicate that 2D‐layered Ti 3 C 2 can greatly enhance the friction‐reducing and anti‐friction properties of base oil, especially with 1.0 wt% Ti 3 C 2 . This novel 2D‐layered Ti 3 C 2 would be a good candidate for lubricating materials to meet emerging needs in practical applications.
