Ti3C2Tx hierarchical stereostructure for innovatively synchronous enhancement on wear resistance and corrosion protection of fabric/phenolic composite liners.

The exploitation of structure-function integrated fabric composite liners has become imperative to address the ever-growing demand for long-term reliability in articulated bearings and bushing blocks within aerospace and heavy duty machinery. However, the durability of liners under the synergistic action of alternating loads and salt spray corrosion remains highly challenging. In this study, monolayer/few-layer Ti 3C 2T x sheets are synthesized via a widely used etching method, then stereoscopic Ti 3C 2T x “maze” structures are constructed by iterative dip-coating within the matrix, thereby synchronously enhancing the tribological and anti-corrosion properties of fabric/phenolic composites. Results demonstrate that the Ti 3C 2T x sheets form a robust interfacial bonding with the resin matrix, significantly improving the mechanical strength of liners. Acting as lubricating phases, the two-dimensional Ti 3C 2T x sheets participate in the friction film, which reduces the wear rate of the composite by 68.27%. Besides, the multi-layered arrangement of Ti 3C 2T x effectively blocks the penetration of corrosive medium via the “maze” effect, the corrosion current density (I corr) of the composite liner-protected steels is reduced from 9.15×10 -6 A/cm 2 to 1.46×10 -6 A/cm 2, showing excellent anti-corrosion performance. It is worth noting that the I corr of composite liner-protected steels maintains a low level (3.99×10 -6 A/cm 2) after prolonged tribological testings. Most importantly, this work proposes a novel structural design strategy for composites, enabling expected wear resistance and corrosion protection, which exhibits strong application potential in high-load and salt spray harsh environments.
